Snapmaker 3-1 square coaster guide for cnc/engraving 8 and 10 cm

thingiverse

A guide designed for the original 3-1 Snapmaker, so that squares of 8 or 10 cm wide can be placed on exactly the same spot each time. Extremely useful for engraving coasters, for example. Print the included thing 4x. The pin fits into the holes in the Snapmaker build plate: the furthest holes for 10 cm coasters, the ones a bit closer to the inside for 8 cm coasters. Use one coaster (or cut one square) and mark the middle on that. use it to position the laser the first time, and use the same origin for the rest of the coasters.
