Just saw this, it's an opensource, 3D-printable, Arduino driven fork mount for small OTAs or lenses. Looks awesome!

There's a topic on here by the creator about it I saw yesterday I believe. And yes, pretty cool.

Here it is.

My experience with 3D printers is that I can do better with some stock, a drill and a file...and it doesn't take a committee of people several days to do the job.  I spent some time broaching drive spacers that one of our 3D printers finally spat out. It would have been weeks faster just to custom cut a part with some sheet and chisel or exacto knife, etc.  I have never seen anything break down so frequently or produce such uniformly poor material as a various 3D printers.  Can't trust the product of 3D prints for anything.  I know they are all the rage, but I have learned not to trust them for anything I actually wont to use...throwaway toys maybe, but nothing else.  Fad, fad, fad.

I disagree. The materials available now are much better.

I printed a worm gearbox in ABS! I haven’t measured the periodic error though...

I dare anyone to produce a worm gearbox with bar stock, a drill, and a file...

3D printing has allowed me to prototype a harmonic drive mount then I used the same 3D files, sent to a CNC machine shop, to make the mount in aluminium. I’ve also created lots of telescope accessories like finder brackets, guide scope rings, Polemaster adapters...

How do you think gears were invented?

You can cut spur gears with hand tools. Don't know how worm gears were cut before hobbing on a lathe was done, but there's a very nice YouTube video about a lathe from the 1700's - so I'm guessing they hobbed gears as far back as 400 years ago.

 

But this is here and now - can anyone here criticizing 3D printers hand-cut (without a lathe) a worm gear and worm wheel in say 2 hours out of any material?

Well, now I have one more idea about how I will use 3D printer when I will buy one. Thank you, OP. I was thinking about buying a new 3D printer for years and finally I've saved enough money to buy it. Right now I have only one problem - which printer to pick. The stuff you mentioned - do you know, what exact printer was used to create it? I have a few printers in my view. The last I've found is impression 3D (https://www.impressi...ateriaux/metal/ - it even can print metal things!), but I'm still in the search of ideal printer. This one is on the top right now. I don't think that I will find something better, but - who knows?

3D printers that can print metal are extremely expensive.

 

Most of us make do with FDM plastic printers. The Creality Ender 3 Pro and Ender 5 are pretty good for the price.

 

I have a (made in USA) Lulzbot Mini with a 6" x 6" bed that was $1295. Been using it for a couple years. I now (also) have a sub-$300 Ender 3 Pro which has a 9" x 9" bed. The Ender 3 Pro has a much bigger work area (that 3" is a big difference) and although it is slower, the print quality is equal or better to the Lulzbot (no wonder Lulzbot went bankrupt..)

 

The Lulzbot is more civilized (auto leveling), has a enclosure, direct drive extruder.. but I could live permanently with the Ender 3 Pro.

Looking at this makes me want to do a larger version on my CNC mill.
