Screw:

Must print 100% infill with supports. 0.2mm layer height highly recommended. Must instruct slicer to print no supports for magnet chamber, which is a bit tedious but it only takes a few minutes. For Cura, select item and go to left-bottom Support Blocker icon, then click on part and a box will appear, which you can reshape, resize, and reposition to block only the area desired. This is an important step. You will need one 15x4mm neodymium magnet for this part (and more for other parts). You will also need a glue or epoxy that will be water resistant to endure washing of parts. This glue will be used to hold in the magnet.

Large Sprocket:

Must print without supports. 0.3mm layer height recommended; 20% infill recommended. You will need one 15x4mm neodymium magnet for this part (and more for other parts). You will need water-resistant glue or epoxy to hold in the magnet.
