Swivel
thingiverse
I started with wanting to make a swivel for hanging plants. Then moved on to designing a multiuse swivel that could be printed without supports. Went through multiple versions and prints. The final version swivel printed in PLA+ at 100 percent scale with "all walls" has been tested at 250lbs static weight for 5 seconds. It was designed to be printed without supports when using a 0.8mm nozzle. If you are printing with a differently sized nozzle you may want to turn on "print supports everywhere". I have not tried to see how small it could be scaled down and still printed successfully but I am guessing you should be able to scale it down or up a little at least.
