planet gear system for tarmo4 (42x versus 2,625)

Hi!

This is the planet gear design for tarmo4. This thing multiply the transmission from 2,625:1 to 42:1 and you got crawler with awesome torque on the wheels.
You need to print:
1x crown2-v2
1x crown1-v2
1x sun-gear-v2
1x ring-gear-v2
6x planet-gear-v2 (or 6x planet-gear-wo-bearings-v2)
6x planet-gear-spacer-v2 (between bearings and crown)
1x 7B
1x 7A
1x Chassis_01A_outerrunner_19mm_extended_motor_mount (if its necessary)

Limitations:
1.the motor mount is shifted backwards around 19mm so you need to print 01A in a modded way (same as Tarmo4 - Extended Gearbox, I have attached 01A to stl files)
2.the gear-mesh creates a lot of noise
3.3542 motor with 1450kv spins up very fast so you need to grease the rings with PTFE grease or else.

you will need Outputgear 09A already printed.

BOM:
6x 3x6x2,5mm Ball Bearings (or you can try to use planet-gear-wo-bearings with a lot of grease but I can't guarantee its lasts for a long time)
6x M3x6 screws

Nylon will be a good choice for a planet gear system, but 07A & 07B can be printed with PLA, PETG

STEP-File included.
