Stacking Bench Cookie Work Riser
A 60 mm diameter, 30 mm tall puck that lifts a workpiece off the bench, so a router bit, a jigsaw blade or a wet paint edge has room underneath. A 16 mm spigot on top drops into the 16.8 mm socket underneath the next puck, so two of them stack to 60 mm and three to 90 mm without sliding apart. Ridges on the top face help the work stay put, and the inside is hollowed with a 45° cone so it prints without supports and uses about 55 cm³.
