A magnetic coupler for 100mm (4") dust extraction hose, this is a clone of a wonderful product, sadly not available in my country.
Used Neodymium Magnet 10x3mm bonded with super glue and accelerator. Magnets must be orientated in alternate N-S orientation for the coupler to work.
The coupler is designed in 2 parts, body and ring to eliminate the need for supports, the ring and body are bonded with super glue. A 10mm reamer might be needed to get the holes accurate, but a tight fitting magnet is an advantage. Be sure to get good build plate adhesion for a completely flat surface.
In the STL named Mag_Coup_Comp the ring and body are integrated but require supports.
For a support free model print the parts labelled: Mag_Coup_Body and Coup_Mag_Ring
