Logarithmic Roller

Hey there, wonderful people!

It's good to be back home and printing all the things once more! The last few models have been shuffled over to the regular directory and the posts updated accordingly.

Some models really do defy photography in terms of demonstrating what they actually are, and leave me puzzling over what angles really show how something works, or even what it is! The Sprocket Box is a good example, as is this one! It's a box, kind of, but perhaps it's more accurate to say it's an exploration of geared motion, or something like that :P

Much like the Exponent Box, this Logarithmic Roller uses non-circular gears - you can see that those pivot points are not even vaguely in the centre of the toothed profiles themselves. However, this time there's a convoluted handle that drives the motion, and the body is made up of the gears themselves, and the moving parts move at different rates thanks to the non-linear relationship between them.

Printing Tips

No supports required! As always with articulated models, make sure your bottom layer is dialled in, and that there are no print artifacts like stringing or overextrusion that might cause moving parts to bind together!

The orientation of the model is front-down for printing, like so:

Further Thoughts

Gears are fascinating things! Shift the arrangement of teeth a little and suddenly the motion changes entirely. Amazing, really! All these non-circular gears are just too much fun :)
