Lego wrapper for TT motor

thingiverse

This is lego wrapper for DC TT motor. It has aligned lego dimensions, which allows to assemble it with standart lego elements. Power motor connected by XH2.54 2pin connector (you may skip it, just drill a bit pin holes and use pure wires). Need four flat head screws - M3x8 and two M3x25 (maybe need to cut them a bit). I used thread in plastic, instead of nuts or inserts, because there is no intention to assemble it many times, and this method shown enough strength for this application. Supports are only needed for connector socket (I set overhang angle > 45 in Cura to not exclude others). I designed it in 4 separate parts to print lego connections without supports - to make them more accurate and easy to join. (and this is a constructor anyway :) Also there is an adapter for TT motor shaft to standard Lego X shaft
