I made these to hold thin materials like paper, poster-board, etc. down to the metal honey-comb bed of a laser cutter. They have 4 generic neodymium magnets embedded in them by introducing a pause in the print just before the top layers begin and adding the magnets into the empty cavity.
I printed these in PLA at 0.25 layer height probably with a 0.4 or 0.6mm nozzle.
Do not use ABS as it will release very nasty fumes if hit by a laser and could damage the laser optics.
The magnets I use are 2.6mm thick by 6mm in diameter. I believe on the store page they were sold as 3x6mm magnets so just pay attention to the actual size. The internal cavity is 2.8mm deep and holds 4 of these magnets side-by-side in a 2x2 arrangement. Overall the anchor is 16.4mm on a side and 4.6mm thick. The top and bottom are flared to make it easy to pick up.
