My Ender 3 is currently out of commission due to getting clogged up during a print. I will, at minimum, need to clean out the heating block and replace the nozzle.

In the meantime, I thought I'd take the opportunity to write about the most recent system for which I've been printing parts.

I call the system 'drywall ports based on a 1+1/4-7-UNC nut and bolt', or 'p2375' (as noted in 3DPrintingData.tef).

How to use it:

1. Drill a 1+1/2″ hole in your drywall where you want a port.
2. Take one of the oval nuts, and with the spikes facing towards you, wrap some tape around the thin parts with an inch or so extends towards you with the stickey sides away from each other.
3. Put some glue (wood glue works, regular white glue probably also works) aroud the spikes.
4. Slide the nut through the hole, hanging onto it so you don't lose it, and stick the tape to the wall to hold it in place.
5. Thread the port into the nut. You can put a couple of #6 screws in the 'spanner wrench' and use it to help drive the port in. The tape should prevent the nut from turning too much while allowing enough movement for it to become centered. The flanges serve to center the port in the hole you drilled, and can also crush down the drywall around it slightly, like a drywall screw, so that the port ends up flush with the wall.
6. Leave it there for a while so the glue can dry
7. Now you have a cool port in the wall.

I'd post a picture of the system in action except that after doing all this I decided that I wasn't up to drilling a bunch of 1+1/2″ holes in the walls and that the whole project was a little bit silly.

I did do it in some scrappy dangling bit of drywall in the basement, but it's not much to look at.
