Z Axis linear bearing spacer for Thing-O-Matic
Description
This is an easy way to fit SW06UU linear bearings to the TOM Z axis and get rid of the not ideal bushings. This solved my problem with inconsistent movement of the Z axis and now it is moving much smoother and it became quieter.
Instructions
Print 4 pieces, on for each of the bearings on Z axis. Put one circlip on each bearing and slide it in to the z stage. Then put the spacer on the linear bearing and put another circlip on top of the spacer. Make sure the spacer are on the outside (top/ bottom) of the Z stage. See picture. Repeat for the other 3 and you are done.
The hole ID is set to 8.3mm to compensate for shrinkage and OD is 22mm. Hight is for my bot and compensated for shrinkage 8.55mm.
These measurments are for ABS filament.

If you're like me and didn't know how those circlips work - do yourself a favor and get a pair of snap ring pliers. I had a hell of a time trying to get them on until I found out about these special pliers that open outward when you squeeze. :)

Looks like a great addition to free up the Z axis a little more.
How's it working out in use?

This looks like a cool solution to my ZAxis issues. Where did you order the bearings from and the circlip, also what size of circlip to fit the bearing?
