I needed a simple model to hang a laptop bag on a door rather than it sitting in the kitchen all the time. This strong hook actually does the trick! Precisely measured for two drywall screws! 

The hook so far, can hold up to 60lbs (w/ PETG) with printing 25% infill, 4 wall loops and at .20 layer height! Can be printed at 45 degrees without supports!

Let me know if you have any questions!
