BB Puzzle

thingiverse

This is a laser cutter project designed specifically for use on the Glowforge. The square puzzle comes together with M3 bolts, long enough to run through every layer. If you skip the screw holes at the corners, it can be glued in place without needing those M3 bolts. The snowflake puzzle is held firmly in place by glue alone. Metal balls used are 4.5mm BBs, commonly shot from airguns worldwide.
