Pi Blade Center for Nimble Rack

thingiverse

**Full build of the Nimble Rack w/ BOM will be uploaded later** ------------------------------------------------------------------------------------------------------- Remix linker isn't working today, so: Remixed from user russross's [Pi 4 1U rack-mount](https://www.thingiverse.com/thing:4125055) pi tray, and the wakoma [Nimble](https://www.thingiverse.com/thing:4520469) rack. -------------------------------------------------------------------------------------------------------- 6U blade center for 3x Raspberry Pi 4s to fit in a Nimble/sixinch rack. For the Pi tray/sled, I just had to set the variable "tray_insert_fudge" to 0.05. From the Nimble, I'm just using their measurements for sizing and positioning. I have spaced the Pi's so that they will fit with a [Raspberry Pi PoE Hat](https://www.pishop.us/product/raspberry-pi-poe-hat/) installed and still have some spacing for decent airflow. It is possible to fit 4 Pi's in the space, but the airflow will be questionable at best. The holes and funnel at the rear are sized for 2x [Noctua NF-A4x20 5V](https://www.newegg.com/noctua-nf-a4x20-5v-case-fan/p/1YF-000T-00096) fans to be rear-mounted. I intend to power them over usb from a power-strip if possible, but will power them from system if necessary. I will update this design if need be. The v-slots for the sleds end so that the sled will protrude slightly from the case, allowing easier replacement. This should also allow for better airflow, as it keeps the sled assembly slightly forward from the air funnel at the rear.
