Differential for 1/10th scale chassis

Here's a sample from my Rich Emporium on Etsy

I designed this to use in the first version of my 3d printed chassis and fits neatly into the front and rear of my 1/10th scale Land Rover model. The main ring gear is reversible for front and rear diffs (so they turn in same direction!)

File naming convention :-
x - number required
s - screws required (2x10mm csk)
pws - print with support
Bearings used are (outside diam x inside diam x thickness) :-
11x5x5 (6 required)
24x15x5 (3 required)

I've added a cutaway version of the case.
