Ball Bearing Spool Holder for Monoprice Maker Ultimate (Wanhao Duplicator 6)

thingiverse

A ball-bearing spool holder for the Monoprice Maker Ultimate. I utilized the same parts used for my Monoprice Select Mini, replacing the component that attaches to the printer with a modified version of the spool holder designed by Garychen99. Requires one 5/16"x5" bolt, one 5/16" lock nut, and three 608 bearings. (Links to the items I used are provided for illustrative purposes, not as recommendations for where to purchase.) To assemble: Print the Spool Holder Beginning (with supports). Then push the bolt through from the hexahedral side of the hole in the middle of the print. The fit should be tight, so a little bit of force may be required. Print the Spool Holder Spacer. Then slide the print onto the bolt. Print one copy of the Spool Holder Center (with supports). Then push a 608 bearing into the side with the flange (should be flush with the end of the print once seated). The fit should be tight, so a little bit of force may be required. Similarly, push a 608 bearing into the opposite side of the print (it will stick halfway out of the print). Slide the print onto the bolt (flange side towards the Spool Holder Beginning). Print a second copy of the Spool Holder Center (with supports). Then push a 608 bearing into the side with the flange (should be flush with the end of the print once seated). Slide the print onto the bolt (flange side away from the Spool Holder Beginning). Print the Spool Holder End (with supports). Then push the lock nut into the hexahedral side of the hole in the middle of the print. The fit should be tight, so a little bit of force may be required. Screw the spool holder end onto the end of the bolt (should be tight enough to lock, but not much more). Spool holder snaps on to the top of the 3D printer. Requires a little bit of force to get it on/off.
