Because I was missing a clamp to fix my lamp onto my desk, I designed one.

The hole for the lamp stub is 13mm diameter. Needed:

• an M8 x 50mm bolt
• two M8 nuts (+ an additional one to block it)

With this bolt, the clamp can grab desk plates with a thickness between 11 - 34mm. Adding a longer one will allow clamping a thinner desk.

The clamp body must be printed with enough infill that ensures its stability. I added a 3MF file for Cura slicer where I added some modifiers to strengten the clamp's body.
