Re: 2465 Fan Collet Thingy
I made my own model from the dimensioned prints, and had some made from SLA. I used a file to make it fit, and have experimented to see how the SLA took the forcibly inserted screw thread. The results were sufficiently encouraging that I've sent a modified variant off for manufacture.toggle quoted messageShow quoted text
A standard home PLA printer definitely won't work. I tried it to assess the relative quality of a nearby 3D printer, and the results were what I expected: dimensionally inadequate, and it easily fractures along the joints between layers.
I don't know about the SLA's long-term stability. I do have SLA with a 2mm pitch thread from 3 years ago that is fine
I don't know about the SLA's long-term stability under heat. I hope it won't get too hot.
The parts could be manufactured in brass or aluminium, but I don't know whether the screw thread would be of adequate quality. If not then manual tapping would be required. They would be more than an order of magnitude more expensive, but still tolerable. Hence I prefer experimenting with SLA.

Where are the 3D files to print my own replacement?
