well I printed a couple last night in abs. Filament got stuck behind the reel on the first one, so that's just a small bowl :-)
basic settings.
.3 layer (wasn't after anything fancy) 60mm print speed, 100 movement, 230 print head, 110 printbed, bowl was 0% infill, whole sphere was 10%

I do have issues with the bottom layers of spheres, they turn out rough and look 'scarred'. The top 2/3rds are brilliant.
I think because the bottom layers go on fast the filament is still pliable and semimelted, for the next layer and doesn't set before the next bit is laid down, so you get weirdness.

I suspect a lower printbed temp and a fan would sort the issue.
Don't get it with cones or cylinders just spheres.

I'll stick a couple of pics up later.

Solidworks files should be run through netfabb before use. That's one of the many things I like about openscad - it pretty much only produces viable 3d printable models.
