Magnetic spring loaded PCB holder

Hi there!
Here is a simple and functional magnetic spring loaded PCB holder. It looks nice and minimalistic, and is very usefull not only for PCBs.

All you need is:
- M3 x 30mm screw
- Ballpoint pen spring (usually about 25mm - 30mm)
- magnet with 6mm diameter and up to 28mm height


Have fun and post a make if you like it!
