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.

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

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

looks good but tolerances a bit big in my opinion

I added a version with less tolerance.

bit tight to separate the pieces but once they are it moves slowly.

Other Issues:it printed fine. but the part we completely apart. when trying to use it, the tolerance was perhaps not tight enough? I'm not sure if it's user error or not. but the parts all fell out.

I'm sorry to hear that. This model is sensitive to extrusion etc. and can be disassembled with a bit of force. You can probably reassemble it. However a more stable (and even more interesting in my opinion) gear fidget is the "binary sun gear fidget" (also with eccentric sun gears).

thank you. I absolutely love your designs and will try the other ones as well. they are absolutely amazing and it prints fine, may have just been a fluke with mine

You are not alone. This model is quite sensitive to slight tolerance variations. I printed 2 on 2 different printers with different filaments and they were fine, so I deemed it ok. I added a note in the description.
