I decided to create a holder for my Arduino Uno and Breadboard because I couldn't find a design that suited my breadboard or it took too long to print. I tested it after printing and it works great! The breadboard can either be clipped into the holder or slided in from the front in either direction and orientation, as I have made indents in the clips to allow for this. Enjoy!I printed this part using these settings: The screws used to hold the Arduino Uno to the breadboard are 4G, 6mm rounded head screws. You can put 9mm screws in also, however not all the way, as the holder isn't thick enough.
