Customizable coupling for Dirt Devil F2 filter. You can set the height and flange characteristics, and much more! If you know of a similar design with different dimensions, this allows you to adjust to fit. With the addition of a retaining ring, it can be mounted through a thin wall. Get rid of the flange and you have a replacement coupling for your standard vacuum -- that was the original idea for this.
This is part of a small vortex canister mod that I am making for a household vacuum cleaner.
For now, use the default numbers or experiment with the variables; I will put comments in explaining them well later.
========== NEW ==========
Make a retaining ring for the default coupler by setting the variables:
Bushheight = 10
Bushdiam = 52
Holediam = 52
Primwd = Primht = Secwd = Secht = 0
This makes a basic bushing (I adapted this part from a bushing script I made).
Thin-walled; try to fill it as much as possible. I printed with 4 walls and 75% infill, but it might be better with 1 wall and 95%+ fill. Needs supports for the overhang. Rafts as your printer requires.
I built this on a Makerbot Replicator 2x, and the F2 filter snaps right in, with a little sanding where the print supports come off.
