Modular Track System

This is a modular track system I made for another larger project I'm working on. The Bogies can be as large or small as needed. I'm working on an integral drive system and will update as soon as I get it figured out. I have also notived that the spacers are a little too short and will need to be lengthened to ensure proper wheel operation.

All of the parts use 4mm screw holes and I've found that 6x32 machine screws fit these very nicely. The tracks require a screw length of 20mm or 0.75in
