The coaster, to scale

About the Coaster Generator

A monogram, a name or a logo on a coaster with a genuinely FLAT two-color face: the glass sits level, the rim catches the condensation.

Free and without an account: type the numbers, watch the live preview, download STL and 3MF files that Bambu Studio, OrcaSlicer and PrusaSlicer open directly. Looking for a ready-made size? The model library has 651 of them, each with its dimensions already filled in.

Printing notes

Questions

Will the inlay face be flat?

Yes. The artwork is cut into the top face and the base prints face down, so the coaster comes off the bed dead flat with the inlay flush.

Hot mugs?

Use PETG. PLA can soften under a fresh mug of tea and takes on a permanent ring.

Which shapes are available?

Circle, square, hexagon and rounded square, any size, with an optional raised lip against drips.
