One more Reuleaux polygons related Thing! These solids called spheroforms have a constant diameter even if they have ridges! Roll them under a book, it will stay horizontal like if it was on 'real' sphere.


This is an extension to 3D of the reuleaux polygons (see http://www.thingiverse.com/thing:62044 and http://www.thingiverse.com/thing:61275).

Like the previous things, I've put a tutorial on how to build them with Inventor and in a parametric way with a Matlab script in http://wp.me/p3gI7M-2j . There is also a video of them in action.

Hi, could you upload the solids as separate files, or arranged in a square? They won't fit my printer this way. Thanks!

Sure, I probably won't be able to do it tonight, but I will do it tomorrow.
I'll write you a mail when it's done.

That would be awesome. Thanks so much!

Just uploaded a Zip with all the shells as separate STL files.
Hope that helps!
