Printrbot Simple 1405 Extruder Fan Mount (50mm Fan)

This is a remake of cap60552's fan mount. His is for a 40mm fan and I had a 50mm so I modified it. It is a great design. I spliced the wiring of that fan into the wiring for my print fan. It comes on and stays on 100% power after layer 2 just like my original fan. I haven't done any long prints with it yet, but it seems to keep everything cool even on short prints.
