3D Printer. You'll probably need to learn a bit of 3D modeling to get the most out of it and it is a hobby in its own right... But man, the amount of little bullshit stuff I had to buy from Amazon that now I print for pennies and to the exact specifications that I need. I made a new door shelf for my fridge to hold my coffee carafe, a door stop, a loop for my bedside table to hold cables, bracket to hold my webcam, hydroponics tower, drawer organizers, pegboard hooks, a plate to cover a weird shaped hole in my wall, a bracket to hang a rgb smart bulb behind my monitor, a phone stand, angled smart doorbell mount, broom and mop hanger, board games, and of course attachments for my 3D printer!!
Hmm... My kia console just broke (literally just the clasp snapped) but to fix it I need a whole console which will cost $400. It's literally just an L shaped piece of plastic that I can glue to the handle mechanism but that L piece went missing. So I took some Legos, glued them into an approximate shape, and then sanded it down to the right dimensions. Console lid now closes, with a fashionable colorful Lego clip lol. If I had a 3d printer...
Haha, that's so smart! Yeah I'm considering printing car accessories, so I bought ASA filament which should stand up to the temperatures in a car and not degrade from the suns UV.
Now that you're into the hobby, what would you recommend to someone that would put good use to a 3d printer? Albeit I don't quite understand the software side of it quite yet.
I've only personally owned the Anycubic Vyper which is supplanted by the Kobra. I've had it for ~3 years with a decent amount of use and abuse. It's very forgiving and when you work on it you aren't worried about breaking a 1k+ machine. That being said, since I use it so much, I've been thinking about upgrading to the Bamboo Labs P1 series for multifilament prints. If you're going to be making smaller prints with finer detail, Like if you're into model/figurine painting, you might want to look into resin printers. They're more of a process to use, but you can get some amazing results.
As for software, I use Blender, but I wouldn't recommend it. It's just what I had previous experience with. People in the space seem to really love Fusion360. But I can't in good conscience recommend an AutoDesk product without a fat asterisk after it. They pull similar DRM shenanigans as Adobe. So checkout TinkerCAD. Or just Google: parametric modeling software.
