A simple wall organizer with possible multicolored text grit information. Holds 50+ sheets of 5" diameter or 125mm random orbit sanding disks. The individual files are in a .3mf format, for easy importing of the separate bodies (main cup and individual numbers) so you can easily go into the objects tab and assign different colors instead of painting manually.

No prime tower is needed since there is no layer with multiple colors. The numbers are raised above the last layer with a different color.
