I’ve got 3 on my list.
- BT-PAN Access Point - Kinda ridiculous, but I’d like to have one. I’ve also found a few BT-PAN-enabled dial-up modems, but I’d have no way to connect those up. Some of those could even be connected to USB printers for wireless printing. Not particularly useful anymore, I just find those devices interesting.
- Dot matrix printer - This one isn’t even as ridiculous. I really love that sound and how the text they print looks. Sadly, if I am looking for new ones, a basic 9-pin Epson dot matrix is around €200. But the ribbons are cheap as chips. In fact, often even cheaper. Just imagine casually handing out a document printed on dot matrix to someone nowdays.
- Nano pocket drone - Something like FQ777-124. Maybe a toy like that is a bit childish, but it still can be fun. In fact I already tried to order this one. From 4 different sellers, twice on AliExpress, twice on Amazon. I never got it :(
Me too until I had access to one through work. I’ve found PLA to be quite brittle and not very useful for anything other than items that sit on a shelf
A lot of it is just knowing how to design around the limitations. I 3D print practical parts all the time and usually don’t have any issues with them. If PLA doesn’t work for what you want to print PETG is pretty easy to print as well and is a bit more resilient.
Polymaker pla pro is a great pla. I have printed plenty of functional things with it and they all hold up really well. If you really need something more durable nylon 6 would be a good option to look at.
