A Tasmanian shaped coaster with a simple, pattern. Tasmania is an Australian state; a small island situated off the south coast of mainland Australia.
An easy print which should work fine on any printer and slicer settings (taking ~ 9hrs depending on slicer configuration). I printed a set using marble engrained filament (from 3DFillies) which made for an excellent colour tone.
Note: You will need to scale it down for it to work as a coaster.
