The file 'Tiny Trak – Print In Place Tread 3D Printer Model' is (stl) file type, size is 357.1KB.
I modeled this as a printable replacement for the Lego x939 treads to be used on Tiny Trak Tank - Micro FPV Crawler. https://www.facebook.com/groups/181517579149618/
I have printed in PLA and works great!
