Remixed the clamp portion to have 3/4" female NTP threads so I can use it with an NTP Loc-Line base. More tricky to setup since you need to run the wire through the hole at the base before soldering it together. I also used some adhesive backed cork sheet to give it more grip on my table.
I used this to assemble the Adam Savage Workbench Light:

I made another remix with a larger hole that doesn't require you to hardwire / solder the wire through the base, and instead using a 90 degree barrel plug adapter. Link here: https://www.printables.com/model/733748-clamp-with-34-npt-threads-for-loc-line-adapter
The author remixed this model.
