Filament guide with rollers for 608 bearings.

This is designed to be mounted outside the printer to guide filament from a spool that is 90-degree turned into the printer. The two vertical bearings simply click into place, the horizontal bearing needs to be installed with the included pin and glued into place if needed.

The two horizontal bearings are almost touching but still have some space to prevent the filament form coming out of the guide, some goes for the top vertical roller.

Mount the guide anyway you like. I used the long holes to make the position adjustable to my spool position.

Use high quality bearings, cheap amazon bearings will not spin properly.
