Printrbot Simple Metal Fan Upgrade V2

thingiverse

After installing my upgraded model, I discovered several critical problems: the massive strain on the tiny CPU fan proved to be too great, the shroud's substantial size made it vulnerable to damage, and its placement interfered with the Printrbot's base when it returned to its original position. This revamped design addresses all of these concerns, notably by incorporating a smaller yet more powerful fan. The upgraded fan boasts greater torque and can much better manage the resulting pressure created within the system.
