Worm Gear + Casing compatible with Lego

thingiverse

Lego Technic/Mindstorm worm gearbox 2x4x3. This design is based on https://www.thingiverse.com/thing:3908311, but I tried to solve the issues with gaps between the main body and the corners of the casing. The original was mainly used for diameters and as a reference. In my design the walls are thicker which solves the gap issue. I've also put the main axles a tiny bit closer to each other to make the gears' connection slightly better. Worm gear is based on https://www.thingiverse.com/thing:149544, but I've also had some issues while printing. There were some gaps between the thread and core of the gear, so now the core part is a little thicker, while still working properly. The last piece of this mechanism is a 24 teeth gear borrowed from https://www.thingiverse.com/thing:4258996. I haven't touched this design as it works properly. I just placed a link for it here to make it easier for you to find all the parts.
