Jumper wire rack for magnet walls

thingiverse

I designed a rack for all my jumper wires (way more than in the photo). Since I have a magnetic wall at my desk I wanted a rack with integrated magnets. The wires fit tight but not too tight. I used 10x2mm neodymium magnets. The model in the photo is made of PETG, but PLA should be fine as well. How I placed the magnets: I didn't use glue or epoxy. I used water pump pliers (I know, very big tool for this case) and a soldering iron. First, I placed one magnet on the top part of the water pump pliers and heated up the magnet by using my soldering iron at 300°C for a couple seconds and while I held the pliers open. Then I put my soldering iron back (for safety) and pressed the magnet gently inside one of the holes using the pliers and let it cool down for a minute. The magnets fit very well. I used the water pump pliers because they can press evenly from both sides, other pliers have a small angle between both sides. I added the Fusion 360 model for remixing purposes.
