Set of adapters to connect 100mm (4inch) hoses.

The male adapter has a protruding lip in order to make a better seal against leaking gases or vocs.

It's also possible to simply connect two female adapters. These are quicker and easier to print but don't feature such sealing capabilities.

Used magnets: 5mm x 1mm (6 each).

If you wish for another version with a different magnet count or size let me know.
