This is a compact and simple bearing press that can be printed on a single build plate without the need for additional parts.

The design has been tested with 608 bearings, but you can easily create and print adapters to accommodate other bearing sizes. 

The main bolt end has an 11 mm diameter, so make sure to print adapters with an 11.5 mm radius indent to help center the press on the bolt effectively. I also recommend printing the adapter as a solid object,
