Tank double idler arm w/ upper idler

thingiverse

I've been experimenting with a unique combination of the double idler arm and the mag idler arm, incorporating an upper idler attached directly to the arm. I'm not aware of any existing design that achieves this specific configuration, but I'm eager to see if it's already out there. The idea behind attaching the upper idler to the arm rather than having it stand alone is to create a more streamlined and efficient system. This setup effectively doubles down on the idler functionality, which should enhance overall performance. As I continue working on this tank design, I'll be able to assess its effectiveness firsthand, but based on my initial calculations, it should work as intended.
