These small magnetic clamps allow for workpieces to be held during laser cutting or other uses for the 3D printer.
Designed for 1mm material height, and uses 6mm dia. x 2.6mm tall neodymium magnets.
I found the most success in printing in the same orientation that they are used, to give a flat bottom surface.
I've included an ASA print of all 4 parts as reference.
