Dust Port for Delta 12" Disc Sander

I got an older Delta 12" disc sander which is a wonderful machine, but it has a really unusual dust collection hookup. You can find the adapters on eBay (either for $$$ in cast iron or $$ for a 3D printed one) so I figured I'd make my own. This fits a standard 4" dust collector hose, which can be run out the back however you want.

This is meant to be simple, quick to print, and no frills though you could definitely add more!

You'll also need either:

• 2x 5/16"-18 bolts (need to be pretty short, 1/2" seems ok), or...
• 2x 5/16"-18 threaded studs (I cut mine to about 3/4" long from one really long bolt) and two washers/nuts to match

The threaded stud/nut option is definitely easier to install in the cramped quarters under the sander.
