Tarmo4 custom

A customization of the Tarmo4 project.
I started taking the updates and improvements and made some changes.

As differential I used the HSP 02024 Diff and HSP 02030 Pinion gear.
I made small changes to the diff box (https://www.thingiverse.com/thing:4840527) reduced the spaces for the bearings and better adjusted the pinion. The original version, in my case, had worn out the teeth.
I added an open diff box if you want to do a transmission test.

I used the metal dogbones (Hsp 188015) with respective adapters.

For the input.stl I didn't use glue but M3 headless screw.

For 18B i used (https://www.thingiverse.com/thing:4483614)

Parts 18B and 18C for big wheels are used if you want to mount 125x70mm front wheels (https://it.aliexpress.com/item/1005002029128681.html?spm=a2g0s.9042311.0.0.9a654c4dzETvOl) model 6638N
