Heavy Duty Planet Gear

This is a reduction box I designed and made with a 8mm output shaft to suit my application (using 2 off these for my belt driven Z axis) . I've included the drawing files feel free to alter as needed. Please not some of the bearing holes have been altered in these files to suit my printer and filament. All these parts are printed in PLA but have also made and have been running 2 of these for about 6 months now in ABS.Everything was printed from my computer using Simplify3D with a 3mm nozzle and
