North pole detector

Precise and sensitive magnetic field detector. With this tool, magnetic poles can be easily identified and the effect of the magnetic field can be visualized. A must for every tech enthusiast and an ideal educational tool. For the tool, I used 13x magnets with a diameter of 6 mm and a height of 1.5 mm, but any other dimension or size can be glued or printed into the case. The printing profile contains a mat for the complete model, it is printed completely without supports. On the second mat, a center case for securing the magnet is ready for printing, which has magnetic poles marked in color.
