Arbor Press

Everything is already oriented correctly for printing for both strength and no supports required. Took me ¼ roll of filament and 4 hours to print. Make sure you have good xy contour compensation values. With 0.2 layer height and 0.42 line width, I used 5 walls, 5 top, and 5 bottom layers with 50% adaptive cubic infill. I printed in PETG.

BOM:

Print 1 of each part except for the BearingAxels, print 3 of those, and only 1 of the racks. One rack is just plastic and the other can take a 10mmx100mm metal rod if you want a metal pressing tip. And it reinforces the strength of the rack.

4x 608 bearings

4x m3 heat set inserts

4x m3x6 screws

Build guide:

Everthing is a tight press fit and should remain that way! For every step I used a hammer to tap things into place. It doesn't matter much if you accidently put too much pressure on the bearings. They don't need to rotate for this to work well.

1. Put the axels and bearings on the left head
2. Attach left head to base
3. Put handle on main gear axel
4. Put the main gear axel through the right head and put on the main gear
5. Press right head onto left head
6. Screw right head onto base
