DIY mouse feet.

Mouse feet and where to find them.

We did an article about repairing the Corsair Scimitar mouse but there was one thing that we forgot to cover upon rebuilding that mouse which is the mouse feet. Otherwise known as mouse skids or even mouse skates. But mouse feet from most manufacturers are made from 0.6mm of substance known as PTFE (Polytetrafluoroethylene or in america it can also go by the it’s copy-written name “Teflon”.) Then, a layer of VHB (very high bond) double-sided tape is applied to the bottom. Would you like to know more?

Why mouse feet of all articles?!?!

The inspiration for this article actually was a series of events that were going on. The first event being that we took our repaired Corsair to a few hotels for random lan gaming. After leaving the second hotel and packing it into our bag we found that one of the mice feet is missing. I initially thought to myself:

Whatever, i’ll just pay $5 for another set from china. Not a big deal.

After a bit of searching. We quickly found out there is no such thing as corsair scimitar mouse pads! Not even knock-off versions!

We could find aftermarket Corsair M65 pads easily enough but not the Scimitar. Oh, and don’t even bother going to Corsairs site. Razer for as much shit as we gave that company at least tried to supply replacement mouse feet as an aftermarket part to their customer.

Corsair just asks if the mouse is under warranty and if not pound sand and buy a new mouse. This is called hyper-consumerism and this is what environmentalists should be fighting. Pushing for a world where you spend a lot of money on a mouse because it does have environmental impact but afterwards it will last you 20+ years because you make it more serviceable.

Instead Corsair and companies like them make people spend lots of money for a mouse that fails in a little over a year. Like my M65, and like the Scimitar that we received. So a giant fuck you to Corsair as well! You’re no better then Razer! My next gaming mouse and keyboard will probably be some china knock-off because I minus well get it from the source manufacturer of practically everything electronic and save some money along the way!

The final aspect of hyper-consumerism at its finest is upon presenting our problem in a forum. There was several other people that said the following:

Yeah, the mouse pads fell off. I just bought another mouse anyways. I go through a gaming mouse once every 3 months. – Forum user of redacted named community

 

Sweet fuck man! It must be nice to spend $200(USD)+ on just mice! Maybe we’re not of the same financial class as these people. But we’ll be happy to accept your “Garbage” broken gaming hardware. Not a problem here!

The great wall.

China lockdown on PTFE

Our next thought process was just to go DIY. PTFE at that gauge is actually very easy to cut with an Exacto blade  So off to work trying to find a manufacture that could sell me a few yards of 0.6mm PTFE in sheet form.

Needless to say. The Cock-blocking was hard. Even on Alibaba of all sites!

There is not a single vendor that will sell you virgin PTFE at that gauge much less one that will have the VHB tape along the backing of said material. The Chinese industrial complex is locked down on this because they realized that they can cut PTFE on a CNC machine and sell gamers a cut out of their mouse feet on a square 2×3 inch for anywhere from seven to twelve dollars. Why give away the business?

Even through they’re tiny we got some PTFE blanks.

Ultimately. I was stuck with purchasing about 8 blank sheets from China for about $16 plus shipping and handling and used my $4 first-time-buyer discount on Alibaba while we were at it.

Anyhow here is a sample of the kind of pads I got. I started to cut into one of them. But you get the idea. Black PTFE at 0.6mm with a CM 468MP/200MP adhesive which is similar to VHB tape. They costed about 90 cents each and they were already cut up into 70mm x 100mm squares which is super shitty.  But we’ll make due with what we got.

Making a template.

HP ScanJet 6300 defect title.

There was a previous article which dealt with me repairing an old HP scanner and some people were probably like:

Why are you spending the time on that old thing? Throw it out!!

Scanners are cool man!

This project actually takes advantage of the scanner. If you have a multi-function printer with a flat bed scanner or a copier which you can e-mail a PDF to yourself that work work as well. The reason why we scan the bottom of the mouse instead of taking a picture with a camera or phone is because the resolution is locked upon scanning. If you scan at 300dpi; That means for every 300 pixels it detects that will be an inch no matter what. This is super-important because we will be using the scanned image of our mouse as a tracing template in a freeware vector program called “InkScape” in a moment.

300DPI-Corsair-Scimitar-BeforeYou may click on the picture above to get the full resolution of what we are working on. However this is our Corsair Scimitar mouse with all of the pads removed. 300DPI is probably the lowest that we would do because in certain places the lined did get a little fuzzy throughout the process. But it’s still readable which is all that matters. We did pull it into GIMP to increase the canvas size to 4×6 inches like our shipping labels. Also, paint the transparent layer purple for contrast while we are working off of this bitmap file.

Building our template in InkScape.

I will attempt to go step by step in the most recent version of InkScape. In the future there may be newer InkScapes that surpass some of the features we are currently doing here. In the event that occurs we’ll try our best to revise the blog to maintain readability. We guess the bonus is you get to use a free piece of software and learn about production a little bit.

InkScape - File and Load

First we will select File and Open inside of InkScape and choose our 300dpi mouse with a resized canvas to 4x6inches.

Bitmap image Import.

Default options are fine here press the OK button.

Inkscape Tutorial - Move object and setup paper size.

Use the Select and Transform objects arrow icon Select and Transform Objects Icon to move our bitmap file off of the page since we shall be using the image as a template for making the mouse pad in the first place. While we are at it lets setup our page size to represent the tiny ass sheets that China gave to us by clicking on File, and Document Properties to pull up the window pictures above. Under Orientation set the Unit size to mm for milometers and add the width of 70mm and the height at 100mm. Once complete you can close out of the window.

InkScape - Lock the Layer

Now click on the menu Object and finally Objects to pull up the object navigation tool. This is similar to the Object Layer tool in Illustrator. Under the “L” Column click the icon to lock our bitmap down. We do this so that the bitmap does not get in the way as we trace our mouse feet.

InkScape - Making your first Object.

Zoom into the first mouse foot we want to trace. You can either use the View, Zoom, and Zoom in. Simply press the “+” key to zoom in. Or my favorite which is using a mouse that has a scroll wheel simply hold the control key down and scroll-wheel up to zoom into the area we are going to trace.

Next we are going to place our first object. Select the create Rectangles and squares icon InkScape Create Rectangles and Squares Icon. and go to at least two corners of the mouse foot. you won’t be able to go to all of them as generally they are always going to be trapezoids or some other weird shape to avoid copyrighting other peoples works.

Now chances are by default you will not got just a line like what we did in the picture above. to fix that click on the Fill and Stroke tab on your right.

InkScape Fill and Stroke 01

Click on the Fill tab and select the X icon for “No paint.”

Click on the Stroke paint tab. For the sake of visibility we’re going to choose this obnoxious peach color but you can choose whatever color you want for your line art.

We then click on the Stroke style tab and change the width to 0.100 mm just to make it visible to us as we are editing our object.

InkScape - Select and drag nodes.

Next we shall click on Path and Union. By making a union will then make all of the nodes visible on our square object. Next, we shall edit the paths and nodes of our object file by clicking upon its icon InkScape - Paths and Nodes Icon.. Then hover over the node that you want to change until it turns red and click-drag it to where you want to be. Right now we are just defining the rough shape as to how we want the square to go around and place our nodes into the center of each curved corner

InkScape - Adding Additional Nodes.

Next to flush out our object we will be adding some more nodes. Click the Insert new nodes int selected Segments icon InkScape - Insert New Nodes Icon. and double-click along the lines close to each of the corners to begin adding nodes.

Continue moving around the added nodes with paths and nodes InkScape - Paths and Nodes Icon. around the outer parameter of the mouse foot. These new nodes will serve as a separation between straight line vector and curved line vectors which is what we will be creating next.

Inkscape-Tutorial- Chang-Node-Type.

Now we can’t get away with straight nodes on this mouse foot. It will look like shit if we go and cut it. So we are going to select the center node in each corner until it turns red and then click the “Make Selected Nodes Auto Smooth” icon InkScape - Select Nodes Auto Smooth Icon. to activate smoothing of the vector lines.

InkScape-Click-Drag-Smoothing Node

You’ve probably noticed that the node near the top had a rather weak curve to the design where it wasn’t covering the entire section of the mouse. If you click on our corner node again you will see two dotted lines come out of it with circles. These are called “Smoothing Nodes.” By click-dragging on the smoothing nodes you can increase the intensity of the curve to your liking. Conventionally, we found that taking the smoothing node and having it line up almost vertically with the standard node below it seems to work out really good.

InkScape - Adding a Circle for the screws.

Finally, lets fix one of the reasons why we had to replace the mouse feet in the first place which is Corsair and Razer love putting the screw holes underneath the pads. Why? Probably because they want you to spend another $50 on a mouse would be a good reason why. So lets fix some engineering neglect.

We know that the hole itself is about 4mm in diameter. So we make a circle by clicking on the “Create Circles, Elipses and Arcs F5” Icon Create Circles Arcs and Elipses Icon.. On the top of the screen we can numerically enter in the X Radius of 2mm and y radius of 2mm. Then Select and Transform Icon Select and Transform Objects Icon to move the circle over our hole. .

Congratulations!

You’ve made your first mouse foot. Repeat these steps for the rest of your feet and you should be doing awesome at that point.

Object Administration.

InkScape Objects Panel.

With only three objects in our file it doesn’t look like a whole lot is going on. But as you start making more feet and more pads this objects panel will get out of hand quickly making the file a complete mess for anyone else to modify it including by yourself! So we need to take proper care of all of the vector objects we bring into InkScape. Don’t think Illustrator people are immune to this and it’s just an InkScape issue! They are the biggest offenders and are in fact worse at administration because of how many objects are coming at them.

Renaming your objects.

InkScape - Renaming Objects.

You can double-click on each of the names and they will highlight which object it is that you are renaming so that you may rename said objects appropriately.

Layering is your friend.

InkScape - Adding a Layer into objects.

Layering helps from a grouping and also an industrial printing standpoint by telling the printer and the finisher what needs to be done on each layer to get the final piece. We won’t be printing anything. But we will be finishing this either by hand with an exacto or on a machine! Select layer and add layer or Shift+Ctrl+N to make a new layer.

InkScape - Layers Added

Now that we have our layers in there we need to assign the objects to the layers.

InkScape - Assign Objects to a layer.

You can select multiple objects in a row by clicking and holding the shift key down or selecting individual objects that you want to do selectively by clicking on the object plus hold the control key as well. As you can see I have assigned the feet and hole to the Kiss-Cut Layer and the Bit-Map Image to the notes layer. Why did I do that? So that when it comes time to print this and/or send it to a CNC cutter robot I could simply hide the notes layer and it leaves just what needs to be cut. No more and no less. Also labeling it “Kiss-Cut” is a method of telling the machine what to do as well during the import process. But if you’re doing this by hand you can label it whatever you like.

Completion and manual nesting.

Inkscape Finishing your mouse and nesting your page.

Repeat the steps above with the rest of your mice feet until your satisfied with the feet. Then Click-Drag each of the feet and copy (Ctrl+C) and mouse-over to where the layout will be printed and past (Ctrl+V). Then using the Select and Transform Icon Select and Transform Objects Icon move each of your objects onto the layout so that you can use as much of your sheet as possible. This is called “Manual Nesting” because we are trying to get the most out of our material for what we made. We probably nested a little too close to the edges but we’ll see. Even if some of them get clipped we will still have at least two perfect sets of mouse feet.

Note: As an experiment I made feet out of the grooves inside of the mouse as well because they were the same elevation recessed into the mouse as the feet were. Not sure if it’s a good or bad thing. But we’ll find out the more we use the mouse!

Cutting out our shapes.

InkScape - Printing Labels for Manual Cutting.

For probably 99.5 percent of my readers which are cutting manually with a fine pointed blade. This would be a good time to print out your nested page and cut it to size to fit your PTFE. I used a thermal printer however you can also use labels that you feed through a laser printer or inkjet and you will accomplish the same task. Place the labels onto the black surface of the nylon. Do not worry about the label sticking to the nylon as it’s protected by a thin plastic coating to prevent any initial scratching during the shipping and manufacturing process.

Make sure you have a new blade! Otherwise it may be difficult to cut those 4mm holes properly.

WTF is kiss-cutting?!?

Kiss Cutting Mouse Pads example.

“Kiss-Cutting” is a technique where instead of using a straight blade which would be classified as a “Through-Cut” or “Thru-Cut” depending on the artist. Kiss-cut has a spring inside of its shaft that as the blade presses down it only exerts a few newtons of force as you move the blade around the substrate. It’s super popular in the sticker making industry! Also, if done correctly the blade cuts clean through what you want but not through the backing behind it.

In China after they get done kiss-cutting something like this they would weave the excess plastics off of the part and throw it into a 55 gallon drum so that it can be re-melted and used again for more sheets of PTFE. Kiss-Cutting this material is rather intense even at 0.6mm so we use to use a heavy spring capable of 20N of force to get it right. The picture above shows that we removed a mouse-set out after machining my part out. and the backside shows the indentations but the blade never punched through the other side indicating a proper kiss-cut.

The Results?

Finished Mouse Pads on the Corsair Scimitar.You can click on the image to get nice and close. But we’re super-pleased with the results. Some of the screw holes were a little bit off and maybe we should’ve kicked it up to 600dpi. However, we managed to completely Rebuild this Corsair Scimitar without the aid of Corsair. That’s both awesome and sad at the same time. Now about the overall performance and feel of the new pads. When we first put them on they felt super-scratchy because the pads are perfectly cut so the edges are square. On a hard-surface pad like what we have it’s no problem!

Fresh cut feet vs. cloth or foam mouse pads.

If you have a cloth or foam mouse pad it’s going to feel like total shit! This is why people on amazon sometimes give aftermarket mouse feet a bad review. This happens because the edges are perfectly square and the edges are not beveled out from the manufacturer.I haven’t dived into a way to smooth the pads. Perhaps with fire to just melt the edges a little? or with a rotary tool with a sanding bit? Since I had a hard mouse mat I played about 12 games of quake 3 on it and the scratching noise went away to almost silence after a while of playing. the edges that were causing the most noise were being buffed down by my hard mat rather quickly! Ultimately feeling like a restored regular mouse.

I consider the rebuild a success!

Final thoughts.

Single set of Corsair M65-Feet on Ebay.Just as a quick note: We were able to make 3 sets of the feet above on a single sheet of 70mm x 100mm.  The the profit is real.

It’s unfortunate that we have to go through such great lengths to keep our mice. That a simple after-market item like mouse-feet is something a gamer would gladly pay $7-12 (USD) to keep their mouse sliding nice and smooth. That now the money is going off to some random manufacturer instead. We guess it’s good for that company that is making the aftermarket pads and bad for Corsair. But in our opinion we have to say:

Tough Shit!

To Corsair! Make better pads! Engineer better mice! Stop being a group of assholes!

This lesson of rebuilding is also a take-away that we don’t need expensive vector drawing software like Adobe Illustrator or AutoCAD to achieve professional results. That as the artist and as the producer. You just need time and effort. So if your mouse feet aren’t being made by anyone. Buy some blanks and make them yourself! It’s up to you to keep your hardware alive as long as you can. Make it last 20+ years!

That’s what server said……
