*UPDATED use v2 files.
A Filament spool holder that uses two 608 (8 x 22 x 7mm) bearings. Uses only 36 gm of filament
It is angled up 3 degrees to compensate for the weight dip of a full spool. Designed to use very little supports.
This model has a twist to lock adapter that accepts a friction fit post which allows the roller to position itself correctly no matter which K1 spool holder you have (Many maker made side spool creations out there have arbitaray tab points orientation).
The ROLLER is designed with a split and a alignment square. Its chamfer at the mating faces makes for a smooth travel over ridgeless interface.
The CHAMBER has various exit holes to help exit debris so roller will keep rolling.
Bearings snap in a very satisfying way into place.
There are also ports under where the bearing seats so if you need to remove, insert a pointed object to drive the bearing out.
Files:
K1 Bearing Roller - TWIST.stl (Use SUPPORTS)
K1 Bearing Roller - ROLLER.stl (No Supports, but BRIM recommended for the square object)
K1 Bearing Roller - CHAMBER.stl (Use SUPPORTS for the peg)
The CHAMBER should friction fit into the TWIST and still be able to rotate with medium force. Use XY hole compensation on your slicer if needed.
You will need two 608 style bearings (8 x 22 x 7mm) https://a.co/d/apXPcV1
