Numpad
thingiverse
This is a custom numpad that I created, designed to fit any standard cherry/kailh switch you prefer. It's meant to work seamlessly with an Arduino Pro Micro as the controller, using QMK firmware installed on it for optimal performance. To replicate my handwiring process, check out this comprehensive guide: https://geekhack.org/index.php?topic=87689.0. For a detailed reference on pin usage, consult this site: https://kbfirmware.com/. Ensure you're using the correct layout by pasting in the following configuration: [{a:7},"","","",""], [{y:0.5,a:4},"Num Lock","/","*","-"], ["7\nHome","8\n↑","9\nPgUp",{h:2},"+"], ["4\n←","5","6\n→"], ["1\nEnd","2\n↓","3\nPgDn",{h:2},"Enter"], [{w:2},"0\nIns",".\nDel"] After creating your custom keymap, flash the hex file to the Arduino Pro Micro using these step-by-step instructions: https://beta.docs.qmk.fm/detailed-guides/flashing.
With this file you will be able to print Numpad with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Numpad.
