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

thingiverse

A custom spool holder for the Monoprice Maker Ultimate is designed and built using similar components as my previous project, the Monoprice Select Mini. A key component is replaced with a modified version of Garychen99's design. The required parts include one 5/16"x5" bolt, one 5/16" lock nut, and three 608 bearings. Links to these items are provided for illustration purposes only. To assemble the spool holder, start by printing the Spool Holder Beginning with supports. Next, insert the bolt through the hexagonal hole in the middle of the print from the top side. It's essential that the fit is tight, so some force may be necessary. The next step involves printing the Spool Holder Spacer and then sliding it onto the bolt. Now, print one copy of the Spool Holder Center with supports. Insert a 608 bearing into the side with the flange, ensuring it's flush with the end of the print once seated. Again, some force may be required for a tight fit. Repeat this process on the opposite side of the print, leaving the bearing to stick halfway out. Slide the print onto the bolt, positioning the flanged side towards the Spool Holder Beginning. Print a second copy of the Spool Holder Center with supports and repeat the same process as before, inserting a 608 bearing into the side with the flange. Slide this print onto the bolt, but position it with the flanged side away from the Spool Holder Beginning. The final step is to print the Spool Holder End with supports and insert the lock nut into the hexagonal hole in the middle of the print from the top side. It's crucial that the fit is tight, so some force may be necessary. Screw the spool holder end onto the end of the bolt until it's securely locked but not over-tightened. The completed spool holder can then be attached to the top of the 3D printer, requiring a bit of force to secure and release it in place.
