Pi Pico Mechanical Keyboard - Tada68 Layout

Update 2023/8/19: Added a wrist rest to go with the keyboard

I really liked 3DPrintSOS's SiCK-68 keyboard so I designed my own with some improvements.

Features:

• More compact
• Cleaner exterior (less seams)
• Prints in less prints on a standard Ender-3 bed
• Uses inexpensive Pi Pico with KMK Firmware

BOM:

• 10x M2 Nut 
• 8x M2*12 Socket Head Screw
• 2x M2*4 Socket Head Screw
• 100x 1N4148 Diode
• 68x Cherry MX style key switches
• Cherry MX Style Stabilizes (3x 2U, 3x 6.25U)
• Raspberry Pi Pico
• Thin wires
• ~300g of filament
• Superglue

Printing:

• All parts are oriented for best results.
• The "Keys" folder has all of the keys split into sets with custom seam positions.
• No supports are required except for the keyplates which need build plate supports.
• 0.2mm layer height.

Post Printing:

• The nut-cavities on the bottom of the case have 1 layer thick built in supports for the holes, poke through them before use.
• Use Superglue to join the pieces (Or use a soldering iron at low temp to weld them)

Electronics:

• The Pi Pico uses KMK Firmware (code.py included below).
• Insert the stabilizers before wiring the keyboard. 
• Refer to this image by wulfboy for wiring.

Notes:

• View the original SiCK-68 cost breakdown (Mostly applicable to this keyboard).
• Helpful video: How to Build MECHANICAL KEYBOARDS by Zack Freedman.
• Layout was made with http://builder.swillkb.com/.
• Pi Pico model used as reference.
• I used Inland Black PLA for all of the parts.
• Fusion and STEP files are included if you wish to modify this.
