Description

Yet another one of my experiments with gear designs (and I'm not done yet). Every gear has a different number of teeth, and the sun gear is not in the center (thus literally eccentric). Still, quite fidgetable.

The hex holes should fit normal hexagonal pencils.

Note: With a bit of force this model can be disassembled. Depending on printer, filament, settings and some luck, the force required varies, and for some the model even disassembled by itself. I'm sorry for that! If it happens, you can probably reassemble it (the ring can be squished a bit to get gears in or out) and thus have some kind of puzzle, but that is selling a bug as a feature…

However, if this model doesn't work for you I recommend the “binary sun gear”, it is more stable and also eccentric (and I find it more interesting).

I added another version ("tighter") with lower tolerances.

Printing: I recommend random seam placement.

I added spots to turn it in to a totally linear rubik's cube. No cheating. No shortcuts. How long does it take to re-align all the spots?

@Dimension_1

If I’ve done my math correctly, it should take 1,680 rotations of the outer ring relative to the center gear.

@2B3D

do you have the files for the one with the dots?

@panhovinkov

I've made a simple handle for this. :)

I'm sorry! Thanks for the feedback. This isn't the first incident; I added a note in the description.

Strength Issue:it falls apart, too easily and you cannot put it back together again :(

@DrJones

Oh... and so many. I'm sorry for that wasted time and filament. Was the the original model or the new tighter one?

@billypengilly

Replying to @DrJones :

no worries :) , will try the tighter model next :)

looks good but tolerances a bit big in my opinion

@DrJones

I added a version with less tolerance.

Nice idea, I like it. I have to be honest, I would have given you the fifth star if there was a chamfer. It's a bit sharp. Maybe I should have calibrated the flow rate, but even a little ironing at the top would have been great.
