Lamp Clamp Table Mount, Version 2

Updated files (IPT & STL) to Rev 4, 23 Nov 20: the L-bolt thread is actually M8 x 1.25. I updated all clearance holes for that thread. They were previously 5/16-18 threads.

Version 2 with some enhancements. My version 1 part finally broke after a few years due to tension + fatigue when the lamp was repeatedly extended very far out from its support. Updates:
- Simplified CAD model
- Bore where the lamp mounts has been reduced for a tighter fit, which should increase the part's longevity
- Added the clamp as a separate printable part
- Removed the horizontal lamp mounting bore for additional strength - I never ended up using it
- Overall strength improvements
- Reduced the installation diameter for the "L" clamping bolt for a tighter fit
- Mount can be screwed into something else (wall, table, etc.) with #10 screws, quantity 4, with a countersunk head

The clamp is available in 2 versions: a "solid" one where you can fill with whatever infill pattern you want, & a "shelled" v
