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 less friction with my spools and having a bunch of unused figit bearings, I came up with this design. It runs very smooth and runs a wide variety of spools. Watch the different infills labeled on the files and use common sense on supports. Kick stand was added later as after I found full spools taxed and broke some axles. How to use: Unscrew original spool holder and nut, keep the nut. Screw on the post, I sometimes had to use a channel lock wrench or clean the printed threads real well. Hammer/slide in bearing to the bearing holder. Some slid in with little effort, some I had to use a paint stir stick and a hammer. placing the bearing on a level surface, put the holder over the bearing and push, if needed grad a small piece of flat wood and hammer the top gently. make sure the bearings are flush with the bearing holder. Insert the bearing holder into the spool holder. Place the combined pieces on the post, using the post like an axle for the bearings. Place the cap over the end of the post. The cap should slide in with a little effort, some twisting will help. Place the kick stand under the cap and make sure the post is at the right height. The kick stand should sit naturally without falling or pushing up on the post. pull the kick stand off as you put the filament spool on, have the kick stand in your left hand and support the weight of the spool as you place it on the spool. GL, after some tinkering this has been a very smooth spool holder for me.
