Switchable Magnet
cults3d
Switchable magnet toy/tool, similar to Magswitch. It isn't particularly strong (easily removable with hand), but it does work. Requires 12 pcs. 6x6m cylinder magnets and 12 pcs. 5x15mm cylinder rods (steel/iron). Insert magnets alternating north/south in both parts. When magnets are aligned, i.e. each rod has 2 north or 2 south facing it the device is on. When they are unaligned, i.e. when a iron rod has both north and south magnet facing it, the device is off. Fairly easy to print without any supports. If slicing with Cura: disable "Fill gaps between wall". https://a360.co/2JA8AE3
