3DPrinting

3D-printing isn't for everyone. However, most of us that got hooked have found ourselves spending 3-4 hours designing a spare part for a broken plastic thing that would have cost us $1 if we bought it.

It's more the trip than the destination for a lot of us. It's creation. It's art.

Some silly things I have downloaded / designed and printed:

• wall mount for a ZigBee motion detector
• detachable shelf for the dredge door
• gardena male connector prototype (going to design a sprayer for our mini greenhouse)
• vacuum cleaner pipe adapter (old attachments to new vacuum)
• Taylor made boxes for RPi and Arduino
• foldable dice tower
• astronaut token tningy for Planet Nine card game
• Custom made box for Exploding Kittens card game
• some cute Groot thing my SO wanted
• modifications for my 3D-printwr

There are numerous sites that may or may not give you inspiration.

I'm still a rookie but here are my five cents regarding cogs mechanics: I'm not sure PLA is a good choice for things you put torque on. Normally Nylon is used and according to what I have understood that's no fun printing. PLA is the easiest. Next Step would be to try PETG. Then there is ABS and ASA which require more from you for a successful print but the reward is a result with a better durability. (Depending on application of course) Also there are toxic fumes when printing those so be careful. Google the different types of plastics and characteristics to get feeling for what to choose for what application.

Good luck.

First, you need to decide if you want 3D printing to make things or you want 3D printers s as a hobby. If the former, I recommend at least $600 and preferably $1200 (Prusa Mk3 or Mk4, assembled) as an entry level machine.

That out of the way, there are a lot of kits out there which are fun to build, from models (Millennium Falcon or Rocinante) to sample ICE engines to fun and interesting mechanisms. If you get good with basic design you can print repairs and interesting things that are hard to buy. I’ve made weird stuff like a nut for a Toto flush handle, a customizable collet for pens in a Cricut machine, and a zero-stop for using the Warthog gaming throttle in a space flight sim. None of those are (or were) sold commercially when I designed them.

Printers are useful but ridiculously slow. A day for a single, 15 cm cubed part is not unusual. It’s a lot like building your own Slackware server. There are pre-built versions (unRaid) and a million uses - but if you don’t have one of those uses and aren’t willing to get your hands dirty and your head deep into forums to set things up and/or fix them, it will be a waste of time and money.
