This is an adapter for the Nilfisk Multi II 30T vacuum that allows you to use magnets for connections. I found the original nozzle awkward when used as a shopvac, so I decided to make this adapter, since the two clips also snapped. This should be a friction fit.
The magnet plate is 65mm on all sides, and the magnets are fit for 10mm width by 2.5mm height magnets. I used strong neodym magnets.
