Pocket Rubber Band Racer

check out the free-wheeling push racer:Please make sure your build plate is clean and free of grease and oil before printing. Although it didn’t happen in my testings, there are reports of it failing near the end of the print. If this happens to you, your build plate isn’t as clean as you think it is. Good luck 🙂A pocket sized rubber band racer, featuring a unibody design that is lightweight and strong; and fun demonstration of how bevel gears work, powered by 2 rubber bands. 1:1 gear ratio.Che
