Double-Brane Mug

Well really more of a minimug-- the inside volume is pretty small compared to the overall size.

Mixed tool flow between Blender and TopMod.

Steps: Took a cube in TopMod and cleaved off the edges to make an octagonal prism, scouped out the inside and subdivided, then did one of those checkerboard scoups from this tutorial: youtube.com/watch?v=fwSV89_syBM With one subdivide to make sure it was still manifold, I took it into Blender and manually added the bridge at the base between the upper brane and the lower one, which will allow it to print. (I couldn't get TopMod to quite grip the faces I wanted.) In addition I sharpened the tops of the holes in the outer brane to make them more printer-friendly.

The Double-Brane Mug is heavily influenced by this one:

(Topologically speaking mine's an inside-out version!)

I've included the last TopMod file before export to Blender for comparison and ease of hacking on it.
