3D prints and Magnets
Found some magnets laying around and decided to put them to use. These neodymium magnets are really strong and come in various sizes. So you can easily make your own refrigerator magnets that actually stay on the fridge!
Here are couple of other things I made.
Simple key hanger
The key holder slides on to two screws on the back, attaching it firmly to the wall. Three ⌀12x3mm magnets are glued to the inside in front to hold the keys.
Cable Holder
Four ⌀8x3mm magnets glued into the slots in the back hold this firmly attached. Holes for the magnets are slightly deeper than 3mm to minimize risk of scratching whatever you attach it to.
