Keychron K4 Wrist Rest (printed and laser cut)

thingiverse

Keychron K4 is an excellent mechanical keyboard, but I soon discovered that its height was causing significant discomfort in my wrists. To address this issue, I designed a wrist rest using a combination of 3D printed parts on my Ender 3 printer and various types of wood and acrylic sheets, which were laser cut on my Glowforge laser cutter. I am also utilizing M3 heatsets and 6mm long M3 countersunk screws from McMaster. Specifically, the following products are being used: https://www.mcmaster.com/94180a331 https://www.mcmaster.com/92125a126 To ensure that my screws are flush with the plates on top and bottom, I employed countersinks. This requires me to drill 90-degree holes in each plate using a specialized drill bit. I already had some acrylic sheets on hand but acquired beautiful wood sheets from the link below: https://ocoochhardwoods.com/scroll-saw-lumber/ After an initial version of this design was created, I decided to redesign it until I was fully satisfied with the results. This led me to reprint all the parts. Please note that my design is still in progress and may undergo changes once assembled. If anyone would like to contribute improvements to the design, I have provided the SolidWorks and STEP files for your reference.
