Ventilador de 120 mm para PC com caixa para Raspberry Pi

#UPDATED to v1.2 04/29/17
A simple two piece, easy printing, easy assembling housing for a Raspberry Pi with a 120mm fan mount above it. Pi 3's run quite hot, and this housing provides plenty of cooling performance as it is open air, has perforation under CPU area, and well, there's a 120mm fan blowing above it. Specifically made to fit an RPI 3 model B with it's own case already, as there's some tolerance between the supports for the pi's placement area and the pi itself. Designed to fit snug with slim cases like http://www.thingiverse.com/thing:1415895 (the one I'm using), but will not fit much bigger. However, it will nicely fit the naked pi. The screw holes for the fan mount are specifically made for M3 screws as that's all I had around, but I am providing the DWG's so you can edit if you desire larger screws (or just drill larger holes). The screw holes for the fan should be snug enough to fit the screws without nuts, but you can use nuts for a more secure fit. Made in AutoDesk AutoCAD 2017 and auto-repaired in Autodesk Netfabb Premium 2017.

Todo:
- remake bottom in AutoCAD (lost it somewhere)
- make bottom perforated for better cooling
- make looser tolerances for pegs
- Make fan mount inner-perimeter circular for more airflow
- Make something better
