Bottom Bracket Bearing Press Drift Tool (6806 - 42x30mm)

This file allows you to 3D print a bearing drift to accurately press bottom bracket bearings into your bicycle frame. Specifically designed for 6806 bearings (42mm Outer Diameter, 30mm Inner Diameter), which is a common standard for many bottom brackets (e.g., BB30, PF30). To assemble the complete tool (as shown in the pictures), simply pair this printed drift with a standard threaded rod, some washers, and nuts/handles. The stepped design ensures that the pressing force is applied evenly to the outer race of the bearing, preventing damage during installation.
