I’ve repaired so many things with it, and engaged in so many new hobbies.
Having a device in your house that can, within reason, magic any item you can dream of into existence is game changing.
Anyway, the 3D printer is coming any day now.
Earlier quoted context omitted.
I started writing the comment with "I highly doubt it", but as I was writing, I think it is a very interesting question. And it might be possible. Like you said, spark plugs require high-heat and high electrical insulation properties. Hence why spark plugs are made out of ceramics (or glass) and metal. Spark plugs also have a heat rating, which indicates how well the plug is able to extract heat from the tip. If the…
I think 3D printing the spark plug itself would be the wrong approach. You could get a better result by designing and printing a jig for making spark plugs - perhaps a couple of pieces? So like, one extruder for making ceramic tubes, then a lathe for working the ceramic while it's still soft? My own messing around with a 3d printer has generally confirmed it's an amazing tool for making jigs of all kinds, but the act…
FYI a 3D printer is super affordable nowadays. Heres a quick guide for home usage: FDM printers: They use a spool of plastic as filament which is heated and layed down layer by layer in a small string, are the cheapest, safest, have a large print volume. On the downside they often break down (e.g. the filament gets jammed) and have a coarse resolution (the smallest details are around 0.1mm). Most popular ones are the…
I got a 3D printer earlier this year for no other reason that it was on sale. I cannot even begin to describe how much fun I've been having with it. Funny enough, I've had to print some of the things on the list. I have a pile of ~10 keyboard legs right next to me on the shelf, they often take a hit when I'm angry at something.
Years ago I owned and worked with tons of different FDM printers. They were always needing a height calibration or nozzle unclogging or something else. Does yours seem to work reliably? Honestly I got to the point where I just thought FDM would never be a reliable tech but I would love it if I was wrong. If yours is reliable, can you tell me what brand it is?
Like all 3d printers they're still fiddly, finicky things in general. There's been a few times where I've needed to spend an hour fettling. But I've owned 3 printers before this and I would say the reliability improvement is at least an order of magnitude in terms of mtbf (where f = fiddling).
I have 3 minis now, 1 with 0.25 nozzle loaded with flex, 1 0.25 nozzle (petg/pla) for decorative/hires and 1 0.4 nozzle (petg/pla) for fast, functional prints. This has mostly eliminated the setup time and calibration required for different "job types".
I couldn't have done this before because just keeping 1 "less reliable" printer working exceeded the free time I was willing to spend on printer maintenance.

Woah. That's way better that I would've expected.
And nobody ever printed adult toys ;)
For the first one I'd recommend doing it without the printer using thick wire and a plastic dip. It will be significantly stronger and (as a result) have much fewer design constraints. 3D printer + minor woodworking + paint/sealant knowledge just kills when it comes to diy. Though I would recommend usinh a 3D printing service, maintaining a prnter can be pot luck with respect to time consumption, and services offer w…
