30 Minute Mechanisms

[eyn2k]

Universal Mechanism set

Currently has only a few dozen, will update very regularly. Next will quickly be worm gears, then cams.

Except for the Frame, all the gears can be printed in under 30 minutes (the handle is a little longer on if you include the axle).



I am currently taking requests, will be back in a few days

Have a look at some more mechanisms, dozens more have been added.

Must see the Rotary to Linkage then back to Rotary using Geneva gears

Nice work!
I am sure they will find application. Also take a look if you can convert rotations to more complex movement paths like 4-bar and Bennett linkages as well as Hoberman type linkages.

That is a great idea, though I have already explored 2 dimensional linkages a few years ago, with Straight line generators, rockers and complex motion paths such as walking robots such as; Jansen leg, Klann leg, Ghassaei Linkage and Tchebyshevs plantigrade machine. ( https://en.wikipedia.org/wiki/Leg_mechanism )
Was hoping to use these for now until I come across more complex linkages. I will provide a great deal, though it will be up to you to use them appropriately and won't delve too deep. They are necessary for other mechanism exploration, such as the rotary, to linkage to rotary Geneva gear in the example above.

Rather than spend more time on 2D linkages, I would like to provide the several basic types of 3D linkage mechanisms, so that you can explore a plethora of combinations at your will. There are many applications for 3D mechanisms that have not been discovered yet due to the immense number of possible combinations and like most discoveries, possible applications can remain unknown for some time.

You can download the files already for free. there is a reasonable explanation of how to use it in the link desciption;
