Magnetic Tool Bar

thingiverse

I needed a magnetic bar that was stronger than the ones sold for toolboxes, so I went out and bought one. My small tools, such as my pincers and tweezers, were barely sticking to it because they use ceramic magnets, which are not very strong. They work great with large tools like wrenches but not with smaller tools that have less ferrous mass. So, I had a bunch of neodymium magnets on hand and decided to make my own magnetic bar. The magnets I used are 9.45mm in diameter and 3.14mm thick, which is equivalent to 1/8" thick and 3/8" in diameter if you're looking for them online at eBay. Each bar holds 11 magnets, and the bar itself measures 195mm long by 15mm wide by 4mm thick. I glued the magnets into the back of the bar with a gap-filling super glue called Hot Stuff Super T. The face of the bar has no visible magnets because I think it looks best that way. There are only a few layers between the magnet and the tool, so most of its strength is still there. If you use the same thickness magnets as me, they will be flush with the back, allowing you to stick the bar directly to your desktop file cabinet without worrying about it slipping or falling off. I think you could hang a 10lb weight on it and it wouldn't budge. Here are my print settings: Printer Brand: LulzBot Printer Model: TAZ 5 Rafts: No Supports: No Resolution: .20mm Infill: 40% Notes: I printed with ABS, using 3 bottom layers, 6 top layers, and 4 perimeters.
