Spent a few hours tonight with adjusting symmetry for cut-outs and hole patterns. I love symmetrical designs where ever it is possible.

I also redesigned the carrier, planet gears, added space for optional bearing, new front cover. Adjusting the output slightly. 

I also did some static load testing to see how the output will handle overhang (mounting) from the bearing since the magnet ring for the (AksIM-2) have a ~0.2mm "ride height"  which means that this part needs to be rigid for the possible loads that may arise. Results ok. 

Anyways with the new changes I was able to hit my 50mm goal (happy  ~48mm) I name this version Rev3.

For the prototype I will also remove the housing fins. 

In a few days I will also receive a full sets of mjf printed parts (Rev2) to play with (Formfactor print only). 

Hardware status:

Arrived: Bearings, dowelpins, titanium screws. 

Ordered. RI60, AksIM-2.

Milling: on hold.
