This is a "bearing" for fidget spinners. It was modeled to be the same size as the 608 bearings commonly used in fidget spinners. The center hole is 8mm, so you should still be able to use thumb pads. The outer diameter is 22mm and therefore should pop into any spinner you might want to put it in. Finally the "bearing" is 7mm tall.

There are 3 different versions. A loose version (called "bearing"), a tighter version ("bearing-tighter"), and a version with 4 cutouts ("bearing-slots").

There is always room for improvement.

Printer Brand:












Prints in one piece. Might have to use a thin bladed object to break it free.


Break In & Lubrication

It's a good idea to use the "bearing" as is for a few days to "break it in". Then, after a few days of breaking it, you can choose to lubricate it with WD40 or light oil. For a quicker break in, you can use compressed air to keep the spinner rotating for extended periods of time.

Why would you make something useful for making other things, then mark it no derivatives? Seems silly.

Well I'll be darned... This whole time I thought I had it marked as CC- non commercial. Thanks for pointing that out!

That makes me happy.

since this is the same dimensions as the real thing I might use this to model a new spinner around, thanks.

Sounds good. Hopefully it ends up working out.

Can I print some and sell in my area?

Sent you a message.

Worked Perfectly!!! This is amazing!!! too bad I didn't find this in time to stop me from buying actual bearings XD

Glad it worked out! At least you'll have an endless supply of bearings now (as long as you aren't out if filament)..

One question. What is the difference between the variation of bearings you made, does one make it faster, slower?

"Bearing" is a version for printers that can't handle as tight of tolerances. Kind of like a 'loose' version. "Bearing-tigher" is exactly as it sounds, it just has tighter tolerances. And the one with slots was designed with thoughts of reducing friction to allow it to spin better, but from what i observed it made little to no difference. So, the slotted version just "looks cool", I guess.

Hi there, the model is pretty cool considering it spins and looks just like a 608 bearing, the problem i am having is that when i pull the bearing off the bed the bottom is one flat piece making it impossible to get it to turn, i have a heated bed and i am printing it with the same settings that you have suggested, any ideas?

Sounds like your nozzle might be a bit too close to the bed. Or you have an over extrusion issue. Try adjusting the nozzle height or set the extrusion multiplier to a lesser value.

What slicer are you using?

nothing specific, because i own an xyzprinting Da Vinci Duo, it makes it so i have a little less control over the printer, but im using XYZWare

Hmm. I'm not familiar with that software. So I'm not sure how much help I'll be. I downloaded the xyz ware manual and thumbed through it quickly. If you enable the advanced settings does it give any options to change the extrusion multiplier or initial layer options?

let me check, did it say where to enable that?

The manual shows it in the bottom left corner after you click print.

Im given the basic setting (infill, layer height, Shell Size, Speed, and Infill type) thats it.

Without using another slicer to generate the gcode, the only other thing I could think of would be to try printing it on a raft. But I'm not entirely sure that'll work.

Using rafts works for me thanks!

Awesome! I hope you enjoy it.
