Things with this kind of shape can be hard to print as the three pillars may be knocked down by your print head. This can happen as the plastic often warps a little bit, so if you have this problem, just use the alternate file that has supports included. These will hold the pillars in place while printing, but they can be cut off quite easily.This file is also a good test for calibrating your printer for things such as oozing and stringing. The Rhino file is also included, without any booleans applied in case you want to tweak it.( Away3D is a 3D engine for the Flash Player that uses Stage3D for playback. Read more here away3d.com )
