Atomic Pi Delux Vertical Desktop Case for passive stack effect cooling

thingiverse

I made a ridiculously long, low production quality video of this thing, with printing tips and a clumsy rendition of the assembly process. https://www.youtube.com/watch?v=O8lmd0dj8ac This is the Deluxe Version of my vertically mounted case for the Atomic Pi SBC. In the photos, it is the pink one. I have a simplified (white in pics) version I will upload shortly and post a link right here when it is ready. It is designed to mount the Atomic Pi vertically, with openings top and bottom to allow passive vertical airflow. It works with (or without) the newer style (narrow) Baby Breakout Board for power. It has slide-in panels on both sides, to reduce print time and offer the opportunity for the maker to explore other materials. I used wood scraps I had on hand, but any 0.25" or 6mm (or thinner) panel might work - polycarbonate might look interesting. It is designed to print with minimal support. There are a few sacrificial layers and bridges which can easily be removed with your trusty blue handle side cutters, or a knife, some break off easily by hand. Some features might look a little better if support is used, but it should not be explicitly necessary anywhere. Flat parts are intended to print flat on their face for easy printing. It is quite strong when assembled. It has accommodations for a USB 2 port wired into the Camera connector. It has accommodations for a 2.5" drive, in two different mounting configurations. Although neither of them have great options for connecting that drive without an external cable to run to the external USB 3 port. At least it is options. It has some optional grills to cover the opening on the top, but I happen to like the look of the heatsink and connectors inside the top opening, especially with a contrasting color for the inner ductwork. The inner ductwork is optional. It probably doesn't help. I'm not a thermodynamicist. The top is theoretically optional. The bolt-on version does add some structural rigidity, but it's not particularly fragile without it. One side can be removed at a time, and it will stand up with the side removed on the triangle brace. It takes a whole bunch of bolts: Each side: Three M4x6mm Two M4x12mm Angle Braces to board: Two M3x30mm Two M3 nuts Structure to Board: Three M3x6mm SSD bracket to structure (optional): Four M3x6mm Top to sides: Four M3x6mm These are the USB ports I used: https://www.amazon.com/gp/product/B07NP7JRYX/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 On my Ender 3 - 0.2mm layer height, 50mm/s, sliced in Cura: The sides take about 5.5 hours each The top takes about 2 hours The structure takes about 2.5 hours. The angle braces take about 1 hour each. The upper duct takes 2.5 hours (optional) The lower intake takes about 2.5 hours (optional) The finisher panel takes about 1 hour (optional) The (optional) grills take about 1-3 hours, depending on the version. The SSD mounts take 1-2 hours, depending on the version. There are many more pics, including a (currently un-notated) teardown and buildup of the case here --> https://imgur.com/a/0fUAhKX
