Keyboard TPU Switch Pad (for Keychron Q1-V2)

After considering purchasing switch pads for my Keychron Q1, I reverse-engineered these thin sheets to sit between the PCB and EVA foam in the PCB-Plate assembly.  They alter the sound of the keyboard by dampening out some of the higher frequencies of the keystrokes and result in a slightly more muted keyboard overall.

Options:

I've created and tested 3 thicknesses: 0.4mm, 0.6mm and 0.8mm

I would recommend the 0.6mm thickness, as it offers a good change in acoustics, without running into switch contact issues (possibly an issue with the thicker 0.8mm sheets)

Each sheet is divided into two halves in order to fit on a standard Prusa i3 print bed, but I've included STEP files for both the halved version (0.6mm thickness), as well as the undivided sheet (again, 0.6mm thickness), in case you wish to make modifications.

Print Settings:

Nozzle: 0.6mm

Use as many solid top/bottom layers as are required to ensure a solid fill.

Change material to “Semiflex” profile and alter the nozzle temperature to be 227ºC.

Otherwise, screenshots are included to document the Filament Settings I used in PrusaSlicer.

Happy printing!
