[UPDATED] Raspberry Pi 3B/B+ Case with Noctua Fan

[UPDATE]: This is no longer a tough assembly! I've divided the top section into two pieces that fit together seamlessly in post-processing. A few drops of super glue will hold it in place or forget the adhesive and use as a detachable cover. As some suggested, I've also added a model with space for GPIO access! This Raspberry Pi 3 B/B+ case was designed to accommodate an internal Noctua NF A4x20 5V fan installation. The fan is mounted at a 5-degree angle to help push air out of the vents located on the side. Aside from the fan (https://www.amazon.com/Noctua-NF-A4x20-PWM-premium-quality-quiet/dp/B071W93333/ref=sr_1_4?ie=UTF8&qid=1533694145&sr=8-4&keywords=noctua+nfa4x20), you'll need: 8 M3 20mm screws 8 M3 nuts All screws and nuts have pre-drilled holes on the model, making installation straightforward. I've included plastic towers inside the model that the board fits onto and locks it in place when the case is screwed together. Remember, you're working with plastic, so don't over-tighten! To install the fan, I cut the yellow wire (carries PWM signal) and connected the red wire to the 5V pin on the board and the black wire to the Ground pin. If you're more ambitious, you could easily write a script to control the fan based on internal temperature using the yellow wire that's connected to a GPIO pin.
