Dummy nut geocache

2 files, one with 3 voids for 8mm magnets, and 1 with 3 voids for 10mm magnets.

If printing at 0.2mm, pause at layer 17 to drop the magnets in then let the print continue.

Best to use supports for the inside, although it's not strictly necessary.

Designed as a false nut/bolt/washer on large structures.

the version using 10mm magnets also has the GC logo on one side.

Took the original nut&bolt, scaled up to suitable size, added the large washer, and the voids for magnets.
