Ceiling Hook

I would print this in PETG or ABS and try and print the hook at an angle for strength. I made this to hang some stuffed animals but it ended up being fairly strong. Be cautious though when hanging stuff from 3d printed parts. It fits a toggle bolt which you attach first and then slide the dovetail joint together. Every printer has different tolerances so be prepared to compensate if the dovetail fit isn't right.

Update- I did a test and the hook failed at around 150 lbs (PetG). Your results may vary of course but it led me to make a ring style variant with more strength.
