This is a remix of a great model by nitronic755. I really wanted a quick connect as my iron needs this collar to come off to swap tips. So I remixed to use magnets instead of screws. Magnets (4x2mm round) just press fit in.

Note: You may want to tuen the heat up a bit more so there is less resistance and the magnets stay snapped

Edit v7 : Added 2mm holes for magnet removal
