Robot arm control box

thingiverse

I wanted to control my eezybot arm using some potentiometers from a scrap soundboard without having to mount the pots directly. So, I simply soldered wires to the pots, ran them through the channel I designed, and attached everything onto whatever surface I plan to mount this on. The parts have been tested, but it's essential to sand the arm's rounded sides for smoothness. I created this design in Sketchup, so some modeling errors might be present (I fixed a few after printing mine). If you notice anything, feel free to let me know, but I probably won't revisit this project. Assembly is quite straightforward: Glue the top and bottom parts together, then sand the edges of the arms. Next, drop the arms through the front face and body until they protrude enough to insert the pot shafts into the arm holes. Place the pots into the arm holes, glue or screw them into place (I designed a hole for an M5 setscrew, but there might be issues with drilling it out cleanly - apply glue only after finding the center position of the pots, if you choose to use glue). Then, slide the arm/pot assembly into the box from the back. You can hotglue the pot into place (optional) and secure it with double-sided tape (also optional). Feel free to share, remix, or make improvements - just give me credit for your work!
