Bearing MR128 8x12x3,5 functional (in 3D)

Search the web, and could not find a functional bearing with this dimensions.

So I create one in a simple way and for fast print.

The bearing has no rolls inside. The inner ring has a tap, so it could not fall out.

I printed the bearing on my Ender 3 pro and P1S without problems in PLA and PETG.

Not every printer and material is the same, so I add the .step file for easyer up- or downscaling for your needs.

To print the bearing use a very low speed (about 20mm/s), Arachne Wall Generator, Z-Seam Random and reduce the flow rate to 90%.

Its used in static models and toys.

Hope its useful for others.

Have fun.
