Summary

It's my design old design.

Low Profile Filament Spool Roller for 608 bearings.
The spool is only 2 mm from the ground.

I have a hermetic case for the filament and it's minimal taller than spool. That's why i needed a low profile spool roller.

You can print 2 or 4 side part to clip them together. I printed only 2 and the bearings sit tight.
You will need also 2 connectors if using only 2 parts. If using 4 side parts you don't need to print the connectors.

The connectors are little bit tight and i had to use sandpaper on the sides.But You can scale it down a little bit. I preferred to sand them so it's really stable.
