architect lamp base (desk clamp)

I bought a cheap architect lamp from amazon, but the original base/clamp of the lamp didn't fit my desk, so I made my own.

The clamp is made of 3 parts. 

1. clamp body: Print laying on the side, so the layers are in the same plane as the bending forces. I recommend at least 3 shells, better 4 for good strength of the part. Infill as you like. I would also recommend to use supports if you have problems with bridging or overhangs.
2. thread insert: Print laying flat, that way the surface of the threads is optimal. Use this part to adjust the fitting to screw and clamp body via horizontal expansion parameter
3. screw: Print with screw head on the buildplate
4. tightening tool: print if you need to. You can tighten the screw with gloves as well.
