Tank double idler arm w/ upper idler

thingiverse

This is a combination of the double idler arm and the mag idler arm with the upper idler attached. Something like this might already be out there but I didnt see it. I liked the idea of attaching the upper idler to the arm instead of standing alone but i wanted a double idler setup. This accomplishes that task. still working on this tank so i cant say how effective it is - should work though.
