Post-Printing

3D printed parts

For bottom bracket removal:

• 2 x collet
• 1 x cup
• 1 x expander rod

For installation:

• 2 x bushing 1
• 1 x bushing 2 (I glued bushing 2 back-to-back with 1 of the bushing 1's)

Additional parts

• ~150mm M8 threaded rod
• 2 x M8 nuts
• 2 x M8 washers. Large washers on the bushings help distribute the load
• 1 x small o-ring or rubber band to keep the two halves of the collet together - 18-21mm OD seems to work."
