BB Balance Wheel 1

thingiverse

Here's a fun, easy print designed for standard 4.5mm friction fit BBs. Simply press them into the holes - if needed, use a tool to help push them in place. This model spins smoothly for over two minutes. It comes in both small and large versions. To get the best results, we recommend printing the Pin with a small brim and setting the minimum layer time to about 10 seconds. Since everything is carefully designed for a tight friction fit, you may need to trim the main pin hole and the pin edges slightly to ensure a snug fit.
