I've had an Altec 670 "Baby Birdcage" ribbon mic for awhile that I picked up cheap because it had been dropped and the plastic birdcage body was smashed and missing a couple of shell segments. I had the idea last night that maybe somebody with a 3D scanner/printer rig could reconstruct the broken plastic cage.
This isn't the big Birdcage with the dual elements (which has a metal cage), it's the smaller, somewhat newer, ribbon only model that achieves multipatterrn functionality with a mechanically shuttered labyrinth behind the ribbon motor. (The ribbon needs replacement too, but I'll deal with that if I can get the body fixed.
Anyone around here into the 3D printing thing? Any idea of what something like this might cost?
Thanks in advance.

It's a great idea and could definitely work. The trick is going to be programming for the printer. A scanner would be cool, but you said the original structure is smashed. I Have no access to 3D technology, so I can't help other than to suggest you look for original engineering drawings. Or glue it back together to make it scannable.

I would try to connect with a Makerspace in your area. They will have the technology and people who know how to use it.

Pretty sure my brother could do this with his 3D printer. He would need to take detailed measurements from a section that's intact. Then mock it up in CAD and print...

There are a few fragmants missing but they could almost certainly be reconstructed quite easily. It could be scanned and necessary adjustments made to the scan to fill in the missing bits. |

Hello
I have a 3d printer as well as being fairly fluent with SolidWorks.
If you still need something done please send me a picture of it and we will see what can be done.
Cheers
Mac

I've been busy with a bunch of stuff, but have not forgotten. I'll try to get some photos of the damaged part (the mic disassembles easily), but my camera phone really iksn't very good, so I don't know if they'll come out OK or not.
I'll need to get some paper with 1/4" squares to provide a scale for the pix.
My thanks to everyone who has contributed so far.
