Stackable Planetary Helical Gearbox for brushless 5010 motor

>> This is a bit of a theoretical model as i haven't been able to testdrive this version yet (waiting for delivery of bearings)! <<This is my remake of Michael Rechtins stackable gearbox using helical gears instead (his uses spur gear). The outer shell is basically the same but i reworked the planet carrier and output hub to use 3 planetgears instead of Michaels 4. In doing this remodel with helical gears I've found much useful information about modeling helical gears in Fusion 360 from Antalz youtube videos about gears in Fusion (How to model Planetary Gears; Requirements, Gear Ratios, Helical/Herringbone (Gears pt 5/7)). Most parts are printed in PETG with a standard mini 0.4 nozzle at 15% cubic infill with 0.25 layer height. Support is needed for most parts.Included are my Fusion 360 model files and a assembly file for a 2-stage gearbox (16:1 reduction (two stages of 4:1)) with bearings placed but without nuts and bolts…Be aware that the model can be very tight and that some sort of lubrication probably is needed for the gears!
