Slice with ~5 extra shells (/perimeters) and zero infill to preserve the crystalline geometry. Low resolution (~0.25mm) should be nice and speedy, but you will need a fairly level build platform.  Created in crisp Faberdashery Arctic White PLA. Object requires ~9g of material (~1m of 3mm / ~3m of 1.75mm filament). Finish by threading with decorative twine if you've printed the hanging decoration... Or simply placing your Cuppa down if you've made the coaster!Faberdashery are releasing daily, seasonal designs for you to print and enjoy.
