The model
The four flakes are called Classic (six arms with branches), Star (diamonds at the tips, hexagon in the middle), Fern (many short branches) and Crystal (two hexagon rings). Each flake stands 0.6 mm above the base, the rim is 2.4 mm wide and raised 1.0 mm. The glass stands on the flake, which covers about a quarter of the inner area; condensation collects in the lower base and stays within the rim.
Printing needs a single color change: base up to 3.0 mm height in the color, then flake and rim in white. For multicolor printers every color is available as its own file, plus a flush version in which the flake is inlaid 0.6 mm deep and the surface stays even.
The holder has a floor with a finger hole and three wall arches with diamond cut-outs. Inside it is 96.2 mm wide, so the coasters have 0.6 mm of clearance all around. Between the arches there is room to grip the stack.
