SlantSpool Spacer

Rhino Reel suggests the SlantSpool for use with their refill coils. See the spool at https://www.thingiverse.com/thing:2850604 (I am not affiliated with Slant3D). However, the Rhino Reel coils are slightly too narrow for the SlantSpool. The extra wiggle room means the filament can slide around and get caught. Use this spacer to make sure the filament is nice and snug. In the images you can see the green spool with the spacer installed and the turquoise spool without the spacer.

Install with the larger diameter on the outside.
