Wacky Pad Hand-Wired Keypad

prusaprinters

<p>I made this oddly shaped macro pad to show off how you can use keyboard-layout-editor.com and swillkb's plate &amp; case builder to create custom 3D printed, hand-wired keyboards.</p><ol><li>Perfect your layout in <a href="http://www.keyboard-layout-editor.com/">keyboard-layout-editor.com</a></li><li>Export it as an svg using <a href="http://www.builder.swillkb.com/">swillkb's plate &amp; case builder</a> -- select "costar only" if using stabilizers</li><li><a href="https://forum.freecadweb.org/viewtopic.php?t=29704">Import svg to freecad</a> &amp; build enclosure around it -- I built a 2-part enclosure with space for a microcontroller in the Adafruit Feather form factor</li></ol><p>Parts you'll need:</p><ul><li>14 keyswitches</li><li>14 keycaps (6 1U, 8 2U) (printable ones in this Thing! but for a tunable version, grab <a href="https://github.com/rsheldiii/KeyV2/pull/114">this version of the keyv2 thing</a> and open it in the openscad customizer)</li><li>14 diodes, if you want anti-ghosting</li><li>wire for rows &amp; columns. I love Adafruit's <a href="https://www.adafruit.com/product/3164">silicone-coated stranded wire</a></li><li>16 pieces of glue-in stabilizer clips from <a href="https://www.thingiverse.com/thing:4747414">this design by ffatolla</a></li><li>A few hundred mm of 0.8mm metal rod</li><li>M2.5 and M3 threaded inserts &amp; screws for assembly (M3 for case, M2.5 for Feather)</li><li>M2.5 nuts to raise Feather so the USB cable clears the cutout, depending on cable&nbsp;</li></ul><p>This pad is wired as a 4x4 matrix with 2 missing keys. I won't cover how to wire a keyboard matrix here, the internet already has plenty of resources. Similarly, I won't cover how to set up the microcontroller, which depends greatly whether you want to use kmk, qmk, or other software.</p><p>I won't lie, this keypad is wacky but not ergonomic. It's a curiosity. But use it to be inspired to create an actual useful layout for yourself!</p><p>Note: I work with Adafruit but made this design on my own time.</p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Prusa</p><p>&nbsp;</p><p><strong>Printer:&nbsp;</strong></p><p>I3 MK3S</p><p><strong>Rafts:</strong></p><p>&nbsp;</p><p>No</p><p>&nbsp;</p><p><strong>Supports:&nbsp;</strong></p><p>No</p><p><strong>Resolution:</strong></p><p>&nbsp;</p><p>200</p><p>&nbsp;</p><p><strong>Infill:&nbsp;</strong></p><p>38</p><p><br><strong>Filament:</strong><br>Generic PLA Any&nbsp;<br>&nbsp;</p><p><strong>Notes:&nbsp;</strong></p><p>Print all parts with the big flat face on the print surface :)</p><p>Keyswitches may need adjustment via the openscad customizer for your printer's characteristics ("stem slop"), don't print all keys out before doing a test fitting!</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>Category: Computer</p>
