3D model description

This is a replacement part for the Ooznest Prusa i3 hot end fan shroud included in , and it fits in with the original nuts and bolts. The new part has places for two 25mm fans. One of them is pointed at the hot end, like in the original. The other fan points towards the extruder barrel, in order to avoid "heat creep" when printing with PLA. I was unable to do long duration PLA prints with my Ooznest Prusa i3 with the original fan shroud, as the filament would get stuck in the extruder. Adding extra cooling in addition to disabling retraction solved the problem.

EDIT: Well, it didn't. I got one successful print with this mod, but after that the heat creep was back. Back to the drawing board.
