Replacement tubes are only about $15 but why spend that when I can just print them!
No, this is a vacuum tube: https://en.wikipedia.org/wiki/Vacuum_tube
That was my first thought as well. I was going to be incredibly impressed if OP managed to 3D print a vacuum tube.
That or get a laugh at a 3D printed dummy vacuum tube in a $1K audiophile amp.
I read that in an Australian accent.
Though point of technically. It’s a tube. And it attaches to a vacuum.
But he did not call it “a tube that attaches to a vacuum.”
too many words, and I’m not cool enough to just call it a “tubeythingthatattchestoavacuum.”
So, Vacuum Tube makes sense.
See, and I went with Patrick. Oh pop culture. Unless, of course, you are Australian. Then, my warmest regards!
I honestly think this is the worst use case for a 3d printer. The part isn’t improved by printing. You can buy the part easily. The cost of modelling time and printing is more than the replacement. There’s a decent chance the replacement part would have arrived quicker than the print took… Sorry to be a bore, it’s better than an octopus or another benchy, I’ll give you that.
Excuse my ignorance, I don’t know much about 3D printer material types / filament resistance, but from a few 3D printed cases for small devices I had, isn’t the plastic brittle? Or the joints of layers. Especially for a long cylinder shape where force is going to be applied to. I dropped 2 cases on the floor and they broke in multiple pieces where 2 layers of filament joined. But granted, their thickness was 2-3 millimeters.
Phone cases should probably be printed in TPU, which really shouldn’t be shattering. (Unless it’s freaking cold outside.
Maximum drop protection. Would come from a hard shell over a squashy TPU case.
There’s really not that much force on these kinds of things, of greater concern is air flow but it looks like op nailed that.
(If op had taken it down to a smaller diameter, cut outs in the nozzle or somewhere would be be necessary- otherwise the vacuum’s motor has to work too hard to get proper air… and they rely on that flow to cool down.)
It depends on material type, print settings and design itself. While injection molded parts are usually stronger, 3D printed parts can survive a lot of stress if built correctly (some printers are built from 3D printed parts for example). But you are right, OPs tubes might not survive for too long (it will break between layers most likely). I wish it survives for many years tho
On the other hand, 3D printing is not only used to build better and cheaper parts, its a hobby for lot of us. The ability to imagine, create a 3D model and build the part at home makes me feel powerfull. Its almost always better (cheaper, stronger, faster) to use other technologies or just buy something, but where is the fun 😄
Yes normally the tube gets inserted into another tube, which is the stuck into another tube or a foot. This leaves a large moment force directly where the tube is pushed into the other tube. Most likely even with careful use, this tube will break very quickly. The layer joint is the weak spot and the type of plastic most likely isn’t ideal.
Vacuum cleaner parts are made from a high impact plastic, something that’s tough but a bit on the softer side. This way it can take a beating without breaking into a million pieces.
3D printing this is cool and impressive to pull off such a high and narrow print. But practically speaking it makes no sense.
The cost of modelling time
my brother in cad, it’s a cylinder. a tube.
Modelling took less than 2-3 hours, and print was overnight so unless Amazon has drone shipments to my area this was faster. Cost in Filament was around $6. All told I think I ended up on the plus side with faster “service” and lower cost.
You also got CAD experience from this so the next one will be faster too.
Man, I’m old. I was wondering how in the heck you 3D printed a glass and metal vacuum tube.
Sintered glass and using solder like filament!
(Okay that might be too ugly, even by my standards….)
Very brave not to use brims on those

Why buy a $15 replacement when I can print one from $20 of filament?!
(I kid)
