Some measurements for dialing in the flange extender.
I went with a 3mm thickness to account for the slight draft to the flange
I didn’t include ID for my variables. Just OD, thickness, flange base and flange extension, an inner dimension and an outer plus base thickness.
Used 97mm for OD.
The depth of the outer flange wall to case I used 13mm to not have it bottom out. Holds on snug with that amount of vcontact area.
The are 10.28mm around the bottom edge of the flange. So that limits the Base thickness. I used 5mm and that was enough. Used 3 perimeters and 25% infill and that seems sturdy enough.
Inside measure to span screen.

And final profile sketch before the revolve.
4 hours and 53 minute print. Opened up some new PLA from MatterHackers and it always seems that you have to do some waste printing or sacrifice some filament before everything works right. Had to cancel and start over as I had issues with the support sticking to the bed. Something is goofy there. This role of PLA is a bit bigger and with the full kilo to it, doesn’t seem to want to unwind easy and fast enough for the quick jerks of the support base. Need to read up on this condition. But it managed to stick down enough for the support base that I continued the print. Happy enough with it.
It works great. Cut a bunch of cardboard and didn’t encounter leaks. It sure makes connecting the dryer tube easy. Thanks @dwardio for the inspiration.
