About this 3D model

A Jig to help line up multiple coasters for batch engraving. I've put in a bit of a tolerance (about 1mm all round each coaster) as they don't have a very neat and uniform edge. I've included the DFX file that can be imported to Lighburn, or similar software to align the laser. Just center your design in the squares and the coaster in the center of each square. STEP file also included for editing, though I don't know much about STEP format… so good luck with that.
