About this 3D model

This was a test article I designed for testing PET+ filament. I needed a thing which had a variety of challenging features so that I could test multiple situations at once given settings, but the thing had to print relatively quickly as it gets tiresome to wait and wait. This thing has four posts of varying height, a very long bridge, and four 'holes'. The three things I try to test are infill success, stringing (between poles) and bridging. So the Blue pictures are PET+ prints (MadeSolid filament) and the black ones are the standard Makerbot Black ABS material.
