Customizable Over the Door Hook

thingiverse

I took one of my old designs and turned it into a customizer. I personally use these hooks to hang towels in my bathroom and jackets in my bedroom. Most people have 30-32mm door hooks, so the STL file should work just fine regardless. The bumps on the design are intended to prevent slippage, but they only provide any real benefit when the door is closed. If you're dealing with a loose fit or heavy loads, you could always use some adhesives as a last resort. Take a look at the picture for a breakdown of what each variable represents - the 'a' refers to an inner dimension that doesn't include clearance.
