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?
