Spinner Bearing Press

thingiverse

After inserting several tens of bearings with your thumb, you'll feel a sharp pain! This press is designed to ease that discomfort using a standard 2" 5/16 bolt and nut. The bolt's hex head secures itself on the bottom part, while the nut remains captive at the top. Simply slide in your spinner, then the bearing, and twist to insert it with effortless ease. Even printing at .3 layer height and with low infill, the parts are surprisingly sturdy and get the job done rapidly.
