An adapter to mount an Arduino Uno to the Aeroquad frame
Very small and easy to print. My Prusa Mendel always has some problems with the first layer though, especially when it had small holes. I printed this at 0.2mm layer height (0.4 for the first layer) and 80% infill because I wanted it strong enough.
I included the .ipt file, it's not designed well but I only needed it to print once.
Assembly: On the aeroquad frame plates there are 4 holes that are 24mm apart. I put 10 mm spacers in those holes to be able to put the cables underneath (see pictures). I bolted the mount plate onto these spacers and put 5 mm spacers on top of the plate, on which I mounted the Arduino with some hard drive screws.
