Raspberry Pi 3/4 MSata usb 3.0 adapter stand

With recent support added for the Pi 4 to boot from USB, I needed a sturdy mount/stand to hold a USB3.0 mSATA adaptor securely beneath it. This design works perfectly with affordable CNC aluminum cases, such as the one found on eBay: https://www.ebay.com/itm/Aluminum-CNC-Enclosure-Case-CPU-Metal-Shell-Suitable-for-Raspberry-Pi-4B-Tool/184123884098 The adaptor used has "nfhk n-30u v2" marked on the board, available on eBay as: https://www.ebay.com/itm/1Pc-Mini-USB-3-0-to-PCIE-mSATA-External-SSD-PCBA-Conveter-Adapter-K-DOLTYPZ/193514517101 When testing, I noticed that the mSATA adapter and SSD run quite warm. Therefore, I strongly advise using a heatsink on the bottom of the adaptor and a copper shim on top of the mSATA drive to keep them cool. For heatsinks, I simply used an old Pi heatsink kit, placing larger heatsinks on the bottom of the mSATA adapter and 20x20mmx2mm copper shims on top of the mSATA drive. You have approximately 6mm of space under the adaptor and 2mm above an mSATA SSD to work with.
