LED lamp magnetic

This is a variation on the LED-adaptor of the 3D-printing-girls. Nice design girls! In the bottem is a small hole for a magnet (dia 6 mm; 2 mm depth). You can use it in a little bottle or dyke with a metal lid of course. If you use a 10 mm LED you got more light than with a smaller one. The battery is a CR2032. Magnets can be ordered at supermagnete.de; type: S-06-02-N.
