That’s good to know ken, I mean that sincerely.
But don’t discount the cheaper printers, they are getting better every day. I can see you having one to make parts to order some day.

So far I haven't been able to test any 3D printed parts because we have been able to do things with CNC in metal and plastic. The cheaper consumer grade printers use the low temperature filament, but I am sure there are more expensive units that can use higher temp filaments, just not sure if a small shop would be able to afford something like that. GE uses 3D printing to make turbine blades for some of their Jet engines so pretty much anything is possible (bridges out of metal in Denmark, and even houses out of cement). Just waiting for it to become more affordable for us obsolete parts makers.

So it is fine for printing small statues that you can put on your desk at your home. But printing a vehicle part, not so much. Think about installing one of these light holders, only to have it melt the first day the van sits in a hot parking lot.

If a pattern, then it seems that the new part would have the flaws of the old part. How were the files generated? From copying a preexisting part?

I found one of mine dangling (broken), and went to order from the usual places and “out of stock”. BusLab (in theory) has them, so I ordered a couple of replacements. Hopefully I won’t get a charge back due to them no longer having any….

On the other housing on the Van I was fixing, the screws are stripped, so that will be a fun repair if or when I have to replace the bulb on that side (if it isn’t working right now, it will flunk Virginia safety inspection.)
