Customizable CAD Keyboard

Description

This custom keyboard was created to speed up my 3D CAD development. My 60 most used commands are now just a click or two away. The keyboard is fully customizable, uses standard components and is easy to replicate since it does not use a PCB, instead everything is 3D printed using the 3DPCB idea.

Features

• 33 keys (5×6+3)
• Easy to customize (printable keycaps with laminated paper inlay)
• Anyone can build it using a 3D-printer (FFF/FDM), common components and a soldering iron.
• QMK firmware (allowing advanced keyboard layout)
• Replaceable keycaps – twist and release
• Using common 6x6mm TACT switches
• Anti-ghosting using 1N4148 diodes
• No PCB required (everything is 3D printed)
• Low activation force (depending on switches)
• Ergonomic – half size keyboard enables shoulder width position of hands.

Bill of Materials (BOM)

• 1x Arduino Pro Micro (or clone)
• 33x 6x6mm tact switches (low actuation force)
• 33x 1N4148 Diodes (can be omitted, with risk of key ghosting when pressing multiple keys)
• Strands of 0.3mm copper wire (from RK Cable)
• PLA for 3D printer
• Micro USB cable
