The chassis of the second version of MyzharBot is functional, but has a few issue. So I am realizing a new chassis based on the v2, and studying the overall dimensions using a 3D CAD.

Tracks modifications
Using spacers / spacers to keep the base of the tracks together was a good solution, but after a lot of research I realized that it is not easy to find 2.5″ M3 spacers (6.35 cm).
Hence, to overcome the problem I have designed three new separators to be realized by laser cutting:
