Magnetic Ring, Feel Electronics

While doubting if I wanted a magnetic implant so I could feel electronics. I made a ring to test the feel out. It works great! I used flexible filament because I thought it would be a snug fit, but it wasn't needed because it turns out I have on idea how to measure fingers properly.

I used a magnet i had lying around with a diameter of 12mm and a height of 4mm. The magnet can also be thinner, but I couldn't squeak more millimeters in the holder without the ring becoming too bulky.

For mounting the magnet, I used some hot glue. PLA is possible, but there is a chance that the ring will partly melted by the hot glue.
