Ball Transfer Units
thingiverse
These are two ball transfer unit designs I made. Both use 4.5mm bbs as the ball bearings. The first uses a 1 inch ball as the main ball, the other uses 4 0.5 inch balls. For more details please read [my blog post about this](http://evansalex.com/2019/04/14/3d-printed-ball-transfer-units/).
