More 3D printed magnetic magnetic connectors.
I'm slowly starting to switch some of my regularly swapped flexy hoses over to 3D printed magnetic connectors.
The first one I did was this one where the 100 mm flex connected to the TS OH guard is also sometimes used on the adjacent router fence.

In photosbelow, the grey flange is 3D printed with an internal thread to match the flexy wire rib so it screws straight onto the hose.
The black flange is a tapered close fit to stubs of 100mm PVC, helped stay in place with a small self tapper.

The grey plastic cap that covered the back flange is used to reduce the amount of magnetic crap sticking to any exposed magnets.
Not so evident here - more so in the next application.
I'm using 8, 10 x 2 mm REE magnets on each flange, mainly because I bought 50 of them for another project a couple of years back and ended up using only a few.
It's fine in this application where one flange sits directly on top of the other but in other orientations a larger magnet may be needed.
Relese is by twist-n-pull.
The next application is the flexy swapped between the, BMH on the underside of the table collection point of the Bandsaw, and the metal dust catcher i use under my grinders and linisher.
Operation is fairly self evident.
The 8, 10 x 2 mm magnets are only just holding the flanges together in the more vertical orientation position on the BS BMH. Might have go for more or stronger magnets -time will tell.

The grey cap has been covering the black flange on the metal catcher bin for about two days but a faint dusting of magnetic dust is appearing on top of the cap above the magnets on the black flange underneath. see red arrows,

A couple of things I've noticed about printing the screw connections for flexy.
The older and more stretched the flexy is, the smaller seems to be its diameter. eg the new stuff on the TS guard seems to be about 109/110mm in diameter where as the older on on the BS is about 106mm, They could also just have been different from the start.
This means just because a threaded flange goes on one piece of flexy doesn't necessarily mean it will fit on another and makes printing the threaded flanges an individual print for each piece of flexy. This sometimes means printing the thing twice or even another time to get a decent fit. I'm slowly getting better at winging this.
