Remixed the original vent connector by hotbrass so I could fit some magnets and screws I already had. Also wanted to create an easy swap system for my resin printer enclosure and airbrush booth. This was designed for 4" dryer vent tubing.

The magnets I used were 5/16" in diameter, 5/64" thick from Harbor Freight
The magnetic vent mount has M3 screw holes for mounting them onto your enclosure, etc.
