I’ve always heard that resin printing is best for miniatures, but if you’re happy with the 0.2 nozzle, I’d stick with PLA. CookieCAD and ProtoPasta both have fun colors. If you really want to branch out, ASA with acetone vapor smoothing could be something to try.

If other things don’t pan out, you could see if the Mankato Maker Space wants it. I’m not really involved, but I’d make the drive for them if they do.

Most things people self host are either torrent clients, HTTP(s) or are game servers. The first one can pick a port arbitrarily. The second can do host routing. The third - some of them support SRV records so you can direct the client to an arbitrary port. It’s becoming less common to need multiple public IPv4 addresses.

Nvidia controls enough of the market that more PSU manufacturers would if Nvidia needed it.

The easiest way to think about it is that the conductor is rated for the current, and the insulator is rated for the voltage. Now, once you get into the nitty gritty, they’re more intertwined than that, but it’s close enough for a surface level explanation.

Not gonna happen for me

I’d buy a printer. If you’re looking for something easy, an assembled Prusa Core One. If you want something more expandable/project-like then probably a Voron.

Edit: a letter

Sounds like a job for tin foil or parchment paper

When you’re actually using the app instead of having the compression artifacts of being screenshot several times, it’s not as bad.
