Library Shelf Marker Holder

I'm a school librarian, and I needed a way to keep my shelf markers organized - specifically Demco Sturdy Colored Shelf markers.

I designed this in Tinkercad. It's about 2 cm tall, 10.5 cm long, and about 5.8 cm wide. There are slots for 25 shelf markers.

I printed this on an Anycubic Mega S filament printer, and a Jellybox 2, both with Dremel filament. Print at 100% or the slots for the markers will be too big or too small for the markers to fit snuggly.

No supports needed, infill at 10%.
