Small print-bed 4 inch dust port and blast gate spacer

I recently bought a dust collector for my woodworking, and wanted to use some blast gates. Unfortunately, I needed more than I had, and also wanted to be ready to add 4" dust ports to any new machines I may get. I made a quick and dirty dust port that could be screwed onto almost anything, and that prints on the bed of a Monoprice Mini and a small spacer so, with some super glue 1/4" plywood, you could turn two ports and a spacer into a serviceable blast gate, though it can sometimes use some help staying 100% open. A magnet would work, as would a pin. The gate I like the best uses thin "hardboard" for the gate, and I just pull it out entirely, turn it around, and shove the duct-tape covered pull-tab end into the gap. My other two use plywood gates and a nylon screw as a retaining pin, but I keep a couple of binder clips nearby to keep them from wiggling and cutting off airflow a bit.

I only tapered the ends, so I actually kind of like these ports better than the Harbor Freight ones. So far they seem strong enough in simple PLA.
