Human: Ball diff for tahustvedt's monster truck https://www.thingiverse.com/thing:2299884 Adjustable without disassembling the diff, just remove the wheel hub and axle and tighten the 3mm hex key bolt. Still in testing (needs adjusting after the first drive). Uses: 1x M3 x25-26mm bolt 1x M3 nut 1x Thrust bearing 4x8x3.5 https://www.banggood.com/XLPOWER-520-RC-Helicopter-Parts-Tail-Thrust-Bearing-Set-p-1229065.html?rmmds=mywishlist&cur_warehouse=CN 1x Bearing 3x7x3 (same as the diff uses) 8x Metal BB's 4.5mm/177 cal 2x Washers 7.5mm x22mm x1.45mm (anything will do long as it's close) 03/15/18 Destroyed 2 axles on the first test, they were a little undersized and accidentally printed them 1 shell with 10% infill. New axles, 0.3 bigger 23/05/18 Added ball and stub axle 05/06/18 New everything Improved clearances on axles and bearings. Sunken nut instead of just screwing the ball diff center bolt into the plastic. A bit thicker under the thrust bearing to stop it sagging. Now needs a longer M3 x25-26mm bolt and nut. I left the hole 2.8mm so it locks the bolt. 10/06/18 New CV balls and stub axles, tighter turning and fixed the off center holes.
