This is a very compact floss organizer. My wife wanted it small enough she could keep one with every kit or bag she kept floss in. This has five spots on each side. Numbered 1 - 5 to mark how many threads you hang from each one. I don't question the design; she doesn't question the printer purchases.
Small one is 1.5 mm thin. 20 mm x 80 mm. Hole is 10 mm x 5 mm.
Larger one is 2 mm thick. 30 mm x 80 mm. Hole is 10 mm x 7.5 mm.
Included is the step file for the larger one. It is parametric. It's based on the Hole length. Still learning Fusion 360, forgive any mistakes.
The pictures are of one I printed on an MK4, with Overture PLA Red.
