Thinkfun Tread Expansion

PRINT IN PLACE TREAD EXPANSION
I have designed a print in place tread set for the Thinkfun Maker Studio sets. The treads are designed to be spaced using the long connectors as a guide. Take the long connector and mark the outside holes as well as the center hole on your box and punch them out. Then print a tread for each side and three spools for each tread. You can design all kinds of vehicles that use treads. I have included a plow for a bulldozer (from a pop-tarts box) and skis to make a snowmobile (from a spaghetti box). You can also use these treads to make a pizza box space shuttle transport and even a Sandcrawler from leftover Amazon boxes.

The best part is these treads print in place. There is no fitting them together, they come completely assembled. The more you play with them the smoother they roll!

I hope you enjoy these treads and come up with some great expansion designs that use them!

**UPDATE** I have added a new tread design called the rugged version.
