The shafts I used were made for these O-rings (on amazon.ca): uxcell Silicone O-Ring, 18mm OD, 12mm ID, 3mm Width, VMQ Seal Rings Gasket, White, Pack of 10 MTG_Shuffler_Shaft_v2 are the re-designed shafts with grooves to hold o-rings (the amazon link above) - if you print these, then don't print the shafts in the card.shuffler.v3mrb-parts.3mf file (right click on them and uncheck printable) nor the card.shuffler.shaft.rubber-band.3mf file if you're using small rubber bands, print the card.shuffler.shaft.rubber-band.3mf file (resized from the previous model) lastly, the shafts in the card.shuffler.v3mrb-parts.3mf don't have a groove, and could be plasti-dipped or used with U-shaped seals that wrap around the disc I was more comfortable in Fusion360, so I used it for the redesigned shaft (o-ring variant)
