Strong Magnetic Hook

thingiverse

This model was built to snugly fit these strongly attractive magnets that I had available. They are actually incredibly powerful, and I don't doubt they could break a finger if one isn't careful just for the record. But hey, let's use them to make a really strong hook for hanging anything on any ferromagnetic surface you can find! Fridge hook for keys? You've got it. Railing hook for your balcony? Probably. Ceiling hook for hanging plants? We'll see. Laptop destroyer of worlds? Yeah, don't get these near your electronics. Seriously. These hooks are awesome and super effective, as seen in the picture above where each coffee can is full of dirt and soaked (got a couple of sprouts starting out in each one - jalapenos on the left and habaneros on the right), and I still have to pull decently hard to release the magnets from the ceiling, so that's my factor of safety. Maybe one day it will rain hot peppers and dirt on my balcony, but that's a risk I'm willing to take apparently. Some advice: If the magnets don't fit in the slots, you can adjust the x/y scale of the print in your slicer or just use some tape to keep them in place if you're not too concerned about aesthetics. I printed these with 30% infill, but you could probably go as low as 15-20% depending on your application.
