Arcade / Push Button Box / Control Box

thingiverse

After watching Makers Muse's video, I decided to experiment with this myself. So I designed the box from scratch in OnShape. ____________ #The Design I designed it parametric and made the dimensions easily editable. You can customize it yourself if you use OnShape: * Height * Size of the buttons * Tolerance between the cover and the bottom part Also, there are a few different versions I added after printing it. It includes rounded corners, a higher bottom for more space and different tolerances. __________ #Electronics I used an affordable Arduino Pro Micro ATmega 32U4, as these can act as a keyboard. Links are in English. **Edit**: Seanrhinehart on Reddit recommended using the Teensy family of products, as they have integration into the Arduino IDE, and specific project types and examples for USB MIDI, keyboard, joystick and other HID applications. So, depending on your intended use, these might be a better choice. The arcade buttons I used are Sanwa OBSF-24, which have such a great feeling and sound to them! __________ #Programm Code I did my best and made it customizable. You can edit the keys / combinations / commands that should be sent to your PC. Writing sentences is also possible. For that see the Arduino Keyboard reference. Also, the used pins can be changed. It's a rather simple piece of code, so check it out and edit it :D I added the program code to the files here in thingiverse. In the current state, pins 2,3,4,5,6,7,8,9 and 15 are assigned to *LEFT_ALT + * *1* to *9* as I did not have any shortcuts assigned to this combination yet. (If you do not want to edit anything just upload this file with the Arduino IDE) #UPDATE: I now used my tolerance test to figure out the best tolerance for a press-fit and it's 0mm to 0.05mm. So, it seems the Prusa MK3 prints really precise. If you own a good 3DP, just use the smallest tolerance and it should fit well. ________ ##Edit / Commentary * I now added a 4x4 version with 0.15mm and 0.05 tolerance. 0.15 seems to be too wide. * As I only printed the 0.2 tolerance version, It would be great if you could tell me how well your print fits. 0.2 was too wide on my Prusa MK3. * Also, I am currently reworking the software, now using the HID-Project-library by Nico.
