Here's my derivative of Mattraptions' desk lamp, with added M3 screw holes. Some parts will still need to be edited and beefed up, but I thought I'd share it anyway. An alternative to anyone who likes screws instead :D
I've also rotated all the parts to lay flat for printing, and should be sliced okay.
Extra hardware needed:
8 x 10 mm M3 screws
2 x 15 mm M3 screws
1 x 35 mm M3 screw
The base still needs work to mount strong, and I've found using two 10mms from both sides instead of one long screw works better and looks a little nicer aesthetically.
