Spool Holder -Fidget Spinner Bearings Driven (Wanhao Duplicator/Monoprice maker select and/or plus)

thingiverse

Needed for this build: two 22 mm figit spinner/skateboard bearings. Looking for reduced friction with my spools and having a bunch of unused figit bearings, I came up with this design. It runs extremely smoothly and accommodates a wide variety of spools. Watch the different infills labeled on the files and use common sense when adding supports. A kick stand was added later as after I found full spools to be too heavy and broke some axles. How to use: Unscrew the original spool holder and nut, keep the nut. Screw on the post, sometimes a channel lock wrench or a thorough cleaning of the printed threads is necessary. Slide in bearing to the bearing holder using a hammer if needed. Some bearings slid in with ease, while others required the use of a paint stir stick and a gentle tap. Place the bearing on a level surface, put the holder over the bearing and push it firmly into place. If needed, grab a small piece of flat wood and gently tap the top to secure the bearing. Make sure the bearings are flush with the bearing holder. Insert the bearing holder into the spool holder. Combine the pieces on the post, using the post as an axle for the bearings. Place the cap over the end of the post, which should slide in easily with a little twisting. Position the kick stand under the cap and ensure the post is at the right height. The kick stand should sit naturally without falling or pushing up on the post. Remove the kick stand when placing the filament spool on, holding it securely in your left hand as you support the weight of the spool. Great results have been achieved with this design after some experimentation, making it a very smooth and reliable spool holder for me.
