I'm not sure what part your referring to Qbranch.

The pyramid shaped part with bevel gears, the planetary gearbox or something else?

Are you involved with CandyFab?

The white gear should be able to spin. It is flexible mot solid.

That's exactly what I was thinking. If anyone can replicate this or find a video, please let us know.

I soooo want to do this!! I just need to figure out how to make one, and with what materials. Better yet.. What machine?

Here is the link for the write up where the design and fabrication are talked about.

I found out a few days ago that my neighbors updated their website......

http://www.protocam.com <---check out their mobius gear

They have been in the business much longer than I have (since 94) and they do high end prototyping.

The easy answer to making this model is to use an additive manufacturing process such as a 3d printer.

One rather interesting way to make this would be to find a really long "rack" (I'm referring to the rack in rack&pinion gears).

Take this "rack" and twist/bend it 180 degrees and connect the two ends.

You would still have to do many calculations to figure out the size needed for the pinion and center gears.
