Rear axle housing from a Toyota pickup. This goes with my third member and other things on thingiverse.
4 - 623ZZ bearings
2 200mm long 3mm rods
4 - m2.5 jam nuts
4 - m2.5 x 5mm set screws
20 - 4x2mm disc earth magnet.
Assembly is fairly straight forward. Glue axle tubes into axle housing. Install axle flanges onto the shafts, glue axle shaft spline to the other end of the 200mm long shaft. Install magnets......
I uploaded the drums and backing plates but I have not printed them due to the size and material required.
