thingiverse

Rotary axis for Snapmaker 3d printer. For best results on all versions, laser burning should be done in the X direction. I have added 3 more stl files. roller_base-1.stl, rods-1.stl, and wheel-1.stl, This is a more stable set up. It uses R188 bearings, 1/4 x 4-1/2 bolt for shafts and the rubber seals are 1"OD X 3/4"ID X 1/8" , i added roller base1. It is the same as original but without side cutouts to make it a little stronger. The project will have to be less then 70mm long, print: 4 rollers 2 connector arms 1 roller base 1 support bracket Hardware: 4 M5-8 screws 4 M4-8 screws 4 105zzz bearings, 5mm id, 10mm od, 4mm wide. 4 #10 o-rings, 1/5" id, 11/16" od, 3/32" wide. 2 5mmx100mm rods. Attach the support bracket to the end of the y axis. 4 m4 screws. Slip the o-rings onto the rollers. Slip 2 rollers onto each shaft. Slide the shafts in to the bearing holes of the roller base . Slide the bearings onto the shafts and press into the roller base. If the roller base cracks at the thin spot of the roller base, it should be okay. (New design in work) Attach the control arms as shown in the picture. 4 M5 screws. The arm bolts should be snug but moveable, There is a small notch on each side of roller base to align with the laser. Make sure all rollers stay on contact with the base during use. I am working on a couple of different variations of the roller base.
