Tarmo4 custom

thingiverse

A customization of the Tarmo4 project. I started taking the updates and improvements and made some changes. https://youtu.be/T3jYBJKJu24 https://youtu.be/Isz29VmBJrw 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. https://www.reddit.com/r/EngineeringNS/comments/ik7nux/tarmo4_metal_differential_and_dogbone_mod/ 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 For shell: https://www.thingiverse.com/thing:4950051 original parts. For Bumper: https://www.thingiverse.com/thing:4537663 https://www.thingiverse.com/thing:4306573 I printed everything with PLA prusament, except for gears, adapters, 18B, 18C, inputs, printed in PC Blend. Of all the files I have also uploaded the step, so that if you want to improve, modify, do and share. OPTIONAL If you do not want to use plastic parts in the dogbone, this is an optional that I have mounted but not yet tested on the dirt road. Purchase: Q.ty 4 dogbone 101 mm metal for RC 1/10 https://it.aliexpress.com/item/32748302598.html?spm=a2g0s.9042311.0.0.27424c4dylrvWY Q.ty 4 cup RC 1/10 https://it.aliexpress.com/item/32891073955.html?spm=a2g0s.9042311.0.0.27424c4dylrvWY For this modification I had to reduce the arms by about 13 mm, print the pieces with the name "metal".
