MPSM v2 Fan Shroud for 40mm Fan for quiet mounting

thingiverse

I really liked the fan shroud developed by conklech (https://www.thingiverse.com/thing:2776707), however I really wanted to have 4 mounting holes for the fan and the fan mount surface seemed to detach from the rest of the model a bit too easily for my liking. There is another remix of this from another user with 4 mounting holes but you can only fit tie straps through two of the holes as they are partially obstructed. This model has a slightly larger fan mount surface in order to have more material/strength around the holes (4 holes, all 4mm) as well as reinforcement around the top of the model. The Noctua A4x20 fan mounted with the rubber mounting feet no problem. I did have to drill the holes slightly in order to fit the rubber mounting feet. I left the model with 4mm holes as it's easy to enlarge the holes but impossible to make them smaller. I printed using supports but that may not be necessary.
