4" Magnetic Dust Collection Coupler

This is a 4" coupling I made to connect hoses in my shop. Each pocket will accept 2 10mm x 6mm magnets. I used these magnets and was able to press fit them with a vice grip. I didn't need to use any glue/epoxy. I printed this on a Prusa MK3S+ with supports for the magnet holes. The supports may not be needed.
