Keyboard Wrist Rest (Chevron)

A wrist rest that looks great next to your mechanical keyboard! Add some personality to your battle station by printing this in your favorite colors!

The wrist rest is broken up into multiple sections with a chevron design. This allows you to print interesting color combinations and also means you can print this wrist rest on smaller printers – I printed mine on a MINI!

It's perfectly sized for my 87 key WASD, and should fit many other mechanical (or normal) keyboards well. I've also provided STL files with different length for 61 keys and 104 keys. If this doesn't meet your needs, you can customize the parameters in OpenSCAD.

Printing Tips

• After importing the STL, use “Split to objects” in Prusa Slicer so you can rearrange the pieces for your printer. For small printers delete the pieces that don't fit (and print them separately).
• I recommend printing the model upside down – this will produce a smooth top side when flipped right-side-up (with the smooth texture of your print sheet) and a rougher bottom.
• I used 0.2mm layer height (structural) settings in Prusa Slicer. Larger layer heights make the top of the print (the bottom of the wrist rest if you print upside down) rougher because of the slope, but this shouldn't be a big deal since it's the bottom of the model.
• Use supports under the alignment pins. Supports aren't needed in the holes.
• 10-15% infill is sufficient.
• Consider using sand or some other material as ballast (pause and fill inside the print) if you want a nice weight.

Assembly

• Glue the pieces together when you're done printing. I used Stick Fast thick CA (cyanoacrylate) glue, but other glues will probably work fine too. A clamp is probably necessary depending what kind of glue you use.
• Try not to let the glue run onto the surface of the model, but if it does you can clean up dried CA glue with acetone (nail polish remover).
• You can buy silicone tape with 3M adhesive cheaply from AliExpress. This makes great non-slip feet. I bought a 300x30x1mm black single-sided self-adhesive silicone strip from AliExpress for $0.79.

This model was developed as a parametric model in OpenSCAD. Want to propose some improvements? Let's collaborate on GitHub! (You can also use the OpenSCAD source files to tweak the length, height, or width.)
