120mm PC Fan Raspberry Pi Housing

thingiverse

UPDATED TO V1.2 04/29/17 A Simple Two-Piece Housing for Raspberry Pi with Excellent Cooling Performance The housing is specifically designed to fit a Raspberry Pi 3 model B, providing ample cooling performance through an open-air design, perforation under the CPU area, and a 120mm fan blowing above it. This ensures that the Pi's high temperature is effectively managed. Designed to Fit Snugly with Slim Cases This housing is made to fit neatly with slim cases like the one from Thingiverse (1415895), but will not accommodate larger ones. However, it fits perfectly with a naked Pi. Screw Holes for Fan Mount The screw holes for the fan mount are designed specifically for M3 screws, which were readily available. The DWG files are provided so you can edit the design to accommodate larger screws if needed. AutoCAD Design and Netfabb Repair This housing was created using AutoDesk AutoCAD 2017 and auto-repaired in Autodesk Netfabb Premium 2017. To-Do List Remake bottom in AutoCAD (lost original file) Make bottom perforated for improved cooling Loosen tolerances for pegs Make fan mount inner-perimeter circular for better airflow Design an improved version Print Settings Printer: XYZ Da Vinci 1.0 w/E3D v6 Rafts: Not Required Supports: None Needed Resolution: 0.25mm to 0.1mm Infill: 10% to 20% Notes: I printed mine with 0.25mm resolution and it turned out perfectly. The ideal temperature for PLA printing is between 215°C extruder and 68°C bed. Infill levels of around 12% are suitable, but 10% should suffice. 20% infill would be the highest I'd recommend unless you're trying to stop a train. Post-Printing Remove Stringing and Flaws Use an x-acto knife to remove major flaws and stringing from the edges and pegs of the housing.
