Full custom 104 Keyboard, Case + Plate

prusaprinters

<p>Update: moving this design back to WIP, as i am not happy with full design once printed, and will rework eventually. Assembly is a pain so attempt at your own risk or remix this first.</p><p>There is an updated case and teensy holder here, also back to WIP still <a href="https://www.printables.com/model/275937-update-full-custom-104-keyboard-case-v2">https://www.printables.com/model/275937-update-full-custom-104-keyboard-case-v2</a></p><p>Is a better V2 case + teensy holder for this system. Make sure to print the updated case over the files found here.</p><p>But the main documentation will still live on this page.</p><p>There is also a version of the plate split into smaller parts in remixes, but the version here is preferred.</p><p>Not intended for beginners. But if you have keyboard switches, diodes, and a controller laying around. You can make your own "normal" full size keyboard.</p><p>Its surprisingly stiff when using new case linked above. Print in the stiffest plastic you got, I went with matter hackers pla printed at a high temp for strength.</p><p>Printed items:</p><p>The plate for mounting the keyswitches was split in half to fit my prusa i3 (printed at 0.3mm)</p><p>The case is 3 parts, Which I printed vertically. (printed at 0.3mm)</p><p>A small sled that holds the electronics. It's a sled to allow assembly and remixing to different controller boards. (printed at 0.2mm)</p><p>Non-printed Items:</p><p>104 Cherry MX or compatable keyboard switches</p><p>104 Diodes</p><p>screws: 21 m3 x 12mm countersunk; 4 m3 x 6mm screws countersunk</p><p>teensy 2.0++ or similar controller with 27ish IO ports (or port multipliers).</p><p>keycap set (as well as spacebar stabilizers)</p><p>wire (mix of 22 gauge and 28 gauge worked well for me.)</p><p>usb cable.</p><p>Kapton/other insulating tape</p><p>Soldering tools.</p><p>Tips:</p><p>Maybe carve a small piece of the plate into a quick test print to check the cherry mx switch tolerance.</p><p>Dry fit everything a few times before wiring to make sure no snags. Designed with .3mm clearance in most fits.</p><p>cherry mx spacebar stabilizers are pinched to start and need to be bent/spread wider to guide smoothly.</p><p>Future Tweaks/small wants, some are fixed in V2 case:</p><ul><li>~~Improve usb location if mousepad is on right it can be in way.~~</li><li>Other sleds for electronics besides teensy2.0++</li><li>~~Better interlocking case body.~~</li><li>The spacebar stabilizer holes are for spacebars I had on hand, there some popular sizes missing.</li><li>Internal wire guides.</li><li>led for capslock+others</li><li>~~Strain relief on controller wiring~~</li><li>~~Adjustable feet to get different angles.~~</li><li>~~Deepen countersink for sled screws.~~</li></ul><p>Licensing / Sources:</p><p>BSD license.
