One of the things you believe when you get a 3D printer is that you can justify the cost by making useful things with it. Well, generally speaking you quickly forget about that idea, because A) it means you have to learn how to use a CAD program and you don’t have the time or ambition to do it because you’re as lazy as I am, and B) There isn’t much out there in pre-existing .STL files that’s of any practical use for the average person. So you end up printing cute little ornaments, weird statues, and lots and lots of pencil holders…
But I finally had a chance to make a real part for a real thing!
Eldest son has, I’m afraid, inherited my fondness for ridiculousness, and has been playing around with laser cutters of late, and needed a peculiar type of nozzle for some kind of air handling system of his laser engraver. So we came up with this…
The nozzles came out about as close to perfect as you can get, except for the one on the far right, which is a result of the filament breaking for some reason about 75% into the print run.
Damn thing actually fits. Amazing…
