Six dice coasters with optional Gridfinity storage bin. Print profiles for PLA Basic, PLA Matte and PLA Wood. 

Coasters are designed with recesses for silicone bumpers because PLA will move around on its own. Almost any roughly 3.5mm thick by 12mm wide (0.14" by .25" wide) self-adhesive bumper should work, however the recesses are oversized to accommodate up to 15mm. Vellax Bumpers are perfectly sized and recommended, but use caution with others like the Scotch while they fit, they are slippery. 

Each pip (the dots indicating the number) is two layers thick, one layer had bleed through.
