GLB Tank Tracks StarForge 3D Modeling Software

Flexible Tank Treads for Rover Builds

GLB, binary glTF in a single file, is what web viewers, Sketchfab and AR apps load fastest, good for showing off a tracked rover design online. GLB Tank Tracks writes a tank tread of any number of 6 mm links, each with a grouser bar underneath and a guide horn on top, hinged on pins with 0.4 mm clearance so the track bends. How many links and how wide each one is are set on the page. The printable part is one 3D Print STL File from StarForge 3D Modeling Software that prints flat with no supports; after 3D printing, each link flexes free.
