Customisable Challenge Coin Holder

I'd seen a few challenge coin holders around and none of them quite met my needs. I've made a few remakes of this already, but this one is now fully customisable: size, number and width of slots, and optionally a small “catch” at either side so coins don't roll out… I've only ever printed this in Wood PLA, but I'm sure it would also look great in other materials. If you're using the customiser (only available through makerworld.com, not via the Bambu Studio app), make sure you drop down the infill. I typically choose 3% adaptive cubic.
