Tank

Tank vehicle designed for multidisciplinary engineering class.
It uses 42 3mmx10mmx4mm bearings and many varying length M3 screws.
It also utilizes 3mm round rod that i trimmed to length required.
For suspension it uses 8 7/32"x1" tension springs

Originally the planetary gears were printed in PLA but they didn't last long so i suggest printing them in PETG for a longer life span.

theres about 104 track links
