1-inch Lamp Clamp Hanger with M16 Screw

I wanted a coat/hat/keys rack but don't really have the space, so I turned my lamp into one. Made for a 1" diameter bodied lamp that I got off of Amazon. Feel free to post remixes with different sizes, the .step files should load in any CAD software and are easy to manipulate.

Hanger printing notes:

• Block supports generation on the thread surfaces. The slicer will say they're an issue but they aren't and you do not want to pick supports out of threads. It's like pizza-ing when you should french fry.
• Let the support tool do its thing on the rest of the part though. 
• The threads work best printed vertically like shown on my build plate.
• Threads are offset to work smoothly with the provided screw and how my printer is tuned. You may have to dial in the thread fit if your printer makes things oversize. 
• .2mm height is what I've been using, not sure how the thread would turn out with bigger layers.
• 4 wall layers
• 40% infill. Can likely use less, but it's what I used and tested.

Screw printing notes:

• No supports
• Print vertically with the handle down.
• .2mm height is what I've been using, not sure how the thread would turn out with bigger layers.
• 4 wall layers
• 40% infill. I wouldn't go much less than this due to strength concerns when torqued.

Use/installation notes:

• Do not crank on the screw really hard. The screw can take a bit of torque, but it's really only as strong as your layer adhesion. So don't go tightening this like it's a solid M16 threaded bolt. I didn't need to go much past snug to hold my stuff.
• Before installation, run the screw through the threads a few times to smooth it out a little.
• The opening in the clamp is big enough to fit a common electrical cord through. I was able to just unscrew the top section of the lamp and slip the clamps on and install the screw. 
• I have tested this hanger with up to 10lbs (1 US gallon jug of water) so far. It can likely take a lot more than that but I didn't have anything else handy that was heavier and easy to hang on it. It's also for designed for coats, not racking free weights. That jacket on the lower one is an armored motorcycle jacket fwiw.
