This is my full setup for the USB Keyboard Plugin in Octoprint. I spent a ton of time trying to get this figured out and I'd like to pass along the work I did to save anyone time who is interested in doing the same setup.

button_cap.STL is for caps to cover the removed NumLock and 000 keys. I just used 3m double sided foam tape to secure the caps. They could be glued as a permanent solution.

pad_icons.SVG are the icons I used for the keys. Just vinyl stickers cut on my Silhouette Cameo 3. I cut .5in x .5in matte black to cover the old key labels and stickered over them with the icons.

I used this cheap numpad from amazon: https://www.amazon.com/Elftear-Numeric-Retractable-Financial-Accounting/dp/B016NM52S8/ref=sr_1_18?dchild=1&keywords=number+pad&qid=1631490632&sr=8-18

E3pro_Klipper.json is my Plugin backup from USB Keyboard Plugin. I should mention that I am running Klipper and I have PSU Plugin configured with a Wemo plug to control from the keypad so you will need to make some changes if you are running marlin.

If you have questions or need help setting up find me on Facebook at The Ornery Maker.
