Ball diff for tahustvedt's monster truck https://www.thingiverse.com/thing:2299884
Adjustable with out disassembling the diff, just need to remove the wheel hub and axle and tighten the bolt with a long 3mm hex key.
Still in testing (needs adjusting after the first drive)
Uses
1x m3x25-26mm 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 its close)

Destroyed 2 axles on the first test, they where a little undersized and accidentally printed them 1 shell with 10% infill.
New axles, 0.3 bigger
5/23/18
Added ball and stub axle
6/5/18
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 m3x25-26mm bolt and nut.
I left the hole 2.8mm so it locks the bolt.
6/10/18
New CV balls and stub axles, tighter turning and fixed the off center holes.
