Koala coasters with a holder!

If you’re not using the added print profile, add all 4 parts of the coaster into your BambuStudio and confirm to load them as a single object with multiple parts (this will ensure all of them are aligned and form one homogenous item while you’re easily able to select all your colors).

The coasters are double-sided, the print is the same on both sides. You can play around with the infill pattern - the print uses object settings to make everything around the koalas (the white part) not have a top of bottom layer, hence what you see is the infill.
