Impossible Gear

This is a response to hepcecob's "Paper Mechanics: Impossible Gear" video.

This animation shows how I imagine the "Impossible gear" might work. There are a few details omitted such as the guides for the gear and the yellow concentric hub as well as the cover which hides the mechanism. I left those out because they cluttered the animation. I haven't yet tried to make it yet but I'm sure it will work. Let me know what you think or post your own designs. As they say, there's more than one way to crack an egg.

Awesome!

You've made the 3D models, convert to stl format & get it 3D printed!

(I use Shapeways for my 3D prints)

@stop4stuff I already have. I printed it out in ABS plastic on the U-print I have at work. It worked really well until I chucked it up in a power drill to see how fast I could spin the internals while holding the gear in place. It ran surprisingly smooth and at a high RPM... for a while...

Most of it survived, but I just haven't reprinted it to post it in a video.

Maybe if you say pretty please.

this poses more questons then it answers...

[eyeammi]

@coatduck And what questions might those be?

[catified99]

how did you make that?

[eyeammi]

@catified99 I designed the model and ran the motion study simulation in a 3D CAD program called "SolidWorks."

Either way you look at it its a pretty neat crafting which required some great thinking and loads of time invested. It certainly deserves some credit even though we might not fully understand it.

@eyeammi Pretty Please ;)

@eyeammi one might be: "could anyone really build that with paper?" i think the spokes just bend in that cover, or it might be photoshopped. but good idea!

man, you are good!!
