This is a reduced-material, rubber-band-based coaster holder designed to hold the splendid Infill Coasters by imdbcool.

Hooks on 3 levels mean holder capacity is adjustable. When "full" it holds 8 coasters. I'm pretty sure it could hold 9, maybe more; the rubber bands should stretch across the top when overfilled.

Doesn't Matter

It's a bit of a fiddly print. I printed with supports and had significant stringing, so cleanup took a while. And the stakes are an adult press fit in the sockets—meaning that it takes pliers plus adult strength to get them to mate. And that's after reaming all the strings out of the holes. The good thing is, no glue required.
