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
Man, I’m old. I was wondering how in the heck you 3D printed a glass and metal vacuum tube.
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.
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.
