Magnet and string lamp

A Lamp which can be turned on by moving two magnets close to each other.

Needed parts:

• 3D printed parts, see attached STLs.
• 12V Power supply
• 12V LED Strip
• End Stop Switch or "Micro Switch" with roller
• 2 pieces of string
• some wire
• 2 Magnets in cylindrical form: D=10mm, L=5mm

• M3 Nuts and Bolts for mounting the microswitch. The main case parts need to be glued, I used "UHU Allplast" glue for plastics. You can use short lengths of filament to align all parts.

  This micro switch would work:

How I Designed This

I used Autodesk Inventor for modeling work and printed the parts on Prusa i3 Mk3.
