120mm PC Fan Raspberry Pi Housing

thingiverse

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 Print Settings Printer: XYZ Da Vinci 1.0 w/E3D v6 Rafts: Doesn't Matter Supports: No Resolution: 0.25mm - 0 .1mm Infill: 10% - 20% Notes: I made mine with .25mm resolution and It came out perfect. Made with PLA at 215 ext - 68 bed temps. Infill around 12% is suitable, but 10% should suffice and 20% would be the highest I would go, unless you are trying to stop a train. Print the parts with the pegs/legs upward. Use a brim if needed, it could help with adhesion issues for both parts. Due to the nature of the model, stringing between the mount legs most likely will occur. This does not mean your printer is bad/malfunctioning. Post-Printing Get rid of stringing/flaws Run an x-acto knife around the edges and pegs to remove major flaws and/or strings.
