About this 3D model

Customized version of http://www.thingiverse.com/thing:53451 I was having trouble slicing this gear bearing with Slic3r for use in my delta bot, I found it kept joining the planets to the outer gear. I upped the clearance to 0.3 and it seems to have fixed it. I'm lifting the Z one layer height when printing this too, which seems to have done wonders for the fine stringing in PLA. As a functioning bearing it's only really very good on the radial loading, as the fine teeth would pop out too easily on high axial loads, it's a really nice showoff piece though.
