Raspberry Pi 4B & HyperPixel 4.0 & Fan Enclosure Mount for Ender 3 V2
Description
I wanted a Raspberry Pi 4B and a Pimoroni Hyperpixel 4.0 touch display running OctoDash / Octoprint. I'm also running V2 Pi Cam and 24" extended length black ribbon. I had a spare slim 60mm fan (11mm thick) laying around and wanted efficient cooling so I designed a fan box that slides onto the RasPi enclosure and routes airflow between the back of the display and RasPi to cool efficiently. I soldered a connector to the back of the RasPi board (normal fan pinouts) for power. I also wanted clean cable management and for the display to float. To get the cables wrapped properly I used a 90 degree USB-C adapter and 90 degree USB 2.0 in order to wrap the cables around the RasPi and hide it from sight. I may also get a down angle 90 degree micro USB cable where it plugs into the ender 3 to minimize the cable exposure. This print is in 3 pieces, the RasPi enclosure, the back side fan box and a faceplate cover. The main RasPi enclosure for the 4B is tight and you may think you can't get the 4B board to fit but you can, it just needs a little care. No additional hardware needed, the screws for the HyperPixel 4 Touch is all you need to fasten into place. I know this may be a very specific design but thought I'd share to see if anyone else can use/remix/etc. Some of the pics were in-flight as I refined and tested, often printing at draft speeds to iterate and adjust, but the STL's should have the final excellent fit, etc. If you want to view my smoke test on the airflow: [YouTube - RasPi 4B + HyperPixel 4.0 Touch smoke test of airflow](https://www.youtube.com/watch?v=xwST8ceSdyQ) [Amazon - 90 Degree USB 2.0 Adapter](https://www.amazon.com/gp/product/B073GTBQ8V/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1) [Amazon - 90 Degree USB-C Adapter](https://www.amazon.com/gp/product/B07M75JXS1/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1) [Amazon - 90 Degree Down Angle USB-Micro Cable](https://www.amazon.com/gp/product/B01787LBF0/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1) [Amazon - 24" Black Pi Cam V2 Ribbon Cable](https://www.amazon.com/gp/product/B07J68TJ7L/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1) [Amazon - JST Plug Connectors for fan](https://www.amazon.com/gp/product/B07PPZGD9S/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) [My Instagram Account Following my 3D Printer Journey](https://www.instagram.com/threeddd.printer/)
