Download Free 3D Model Linear bearing compatible with sme8op but with 623 bearings 3D Print Model

Summary
This is the replacement for my prusa i3 linear bearings. The ones I had originally were verry bad and loose. Now it works flawlessly.
I attached the bearings using m3 screws, but it should be possible to mount it with original m4 screws (but I am not sure, please be warned).
