Update Apr/3/2016: changed the orientation of the model to a better printing orientation (two rods are along the printing bad, similar to helicopter landing gear. I printed a new one today using Hatchbox yellow ABS with support material and got very good results (slicing with Simplify3D).

This is a customizable holder for Flashforge Creator Pro filament guide tubes. It holds the end of the tubes away from the printer case to avoid entanglement and in an angle that fits the Makerbot acrylic dome http://store.makerbot.com/parts-accessories/replicator-2-2x/x1-rep2x-top-enclosure.html which is superior to the Flashforge stock dome.

I got best results when printing it in the orientation in the .stl file here with material support. I used ABS, bed temperature of 110 deg and nozzle temperature of 230 (higher nozzle temperature improves the layer bonding and overall strength).
