3D Cactus shaped magnet for your fridge or bulletin board.
Fits an 8mm diameter, 3mm high cylindrical magnet.
I glued in the magnet but that is not mandatory.
Printed with Prusament PLA Blend Lime Green at 0.1mm layer height with 0.4mm nozzle on a mk3s+
Use a brim to make sure it sticks to the build plate, as the side arms may curl up a bit during printing and the nozzle can drag the print off the build plate without the brim.
No support needed, but its possible that the magnet will portrude a little bit. If this bothers you, clean out the hole before gluing the magnet in.
