Any chance you can post a .step file of this? I would like to have it in much much higher resolution for CNC milling.

Producing a STEP file would require basically starting over, but I want to do it and it's in the project queue. I will let you know when/if it ever happens.

Hi Sean,

Is it true that there are many possible Gomboc ? Have you seen different shapes ? I remember reading something about a shape that was very close to a sphere.

That's correct. I don't have their original paper handy, but your memory jives with mine. They had some kind of computational or numerical method that produced a G
ömböc that was very close to spherical. The popular shape, the one I attempted to replicate here, was actually made by a trial-and-error process, if memory serves.

Cool shape! Never heard of a G
ömböc before.

It very very, tiny though. Can you double check the size?

What are you opening it with, if you don't mind my asking? Cheers- SMR

Skeinforge, the tool most home 3d printers use to slice up models. It assumes that STL units are in mm. I also tried importing it into sketchup with units=mm and that reports that the model is 0.1mm tall.

A common typo is for people to export with units=inches. I tried scaling up the model 24.5x in sketchup but even then, it's only 3-4mm tall. :(

No. Wait.. I may be full of it.. Importing to sketchup with units=inches makes it ~45mm tall.

Never mind. Ignore me.
