Flexible One-Piece Tracks for MR6 Tank

thingiverse

I found the tank tracks for Timmiclark's MR6 - Mini Prototyping Tank Robot (https://www.thingiverse.com/thing:2753227) to be extremely time-consuming to assemble. Each of the 64 pieces required needs to be pinned together into a track by creating small pins out of filament, which proved to be an arduous task. These tiny pins generated excessive friction, causing the tank to slow down significantly, and eventually broke off, necessitating replacement. I replaced them with 1.75mm rebar wire, which is substantially more durable, but still produced a considerable amount of friction. This design was my answer to the friction problem. It features one continuous circular track that can be printed in most any flexible or semi-flexible material, such as Ninjaflex/Semiflex, eliminating the need for links and consequently removing friction between them since they are no longer necessary. Simply print the track, then pull it over the cogs on the tank and it will securely fit into place.
