silakka54 Case with Wrist Support

*This design is not complex at all, but any 3d printed assembly requires a well calibrated 3d printer!

**This case is specifically designed for the Aliexpress v1.3 PCBs. Other variants might work as well, but those have not been tested.

Highlights

• Friction fit the case together, no fasteners parts needed!

• 3D printable wrist rest! I use this myself, SERIOUS!

• You can also purchase the wrist rest I'm using from Amazon.

• You can also use heatset inserts and bolts to hold the case together.

• Buttons for the RP2040-zero.

• LED hole for the light to shine through.

• Minimal supports needed.

• No wrist rest variant!

Bill of Materials if Fasteners are Used

• 16 x heatset inserts M2mm x L3.0mm x OD3.2mm

• 12 x M2 Socket Head Cap Screw L10.0mm

• 4 x M2 Socket Head Cap Screw L14.0mm (MCU area)

Print Settings

• Any print settings will do really, but try to use the settings provided in the .3mf file.

• Supports only needed for the top part, for the USB hole. The printed supports measure roughly 3 mm x 4 mm x 15 mm. If your printer is good at bridging, you don't need any supports.

• 5 walls, 5 top and bottom layers, 20% infill.

Notes

• These are the wrist rests that I'm using, only ~CAD$10 for both: https://www.amazon.ca/dp/B08ZY2WFHX

• Other wrist rest sizes will also work. Print out this one (you don't have to print the whole thing) and compare it to what you have. It just needs to be close enough, an exact match is not necessary.

• You can find images of the v1.3 PCBs [here](https://github.com/Squalius-cephalus/silakka54/tree/main/step/pcb_aliexpress_V1.3-images).
