If you have your Pi running off SSD having them seperate isnt ideal so I made this ‘basic’ case to house both the Pi5 and a UGREEEN SSD to USB adapter case. You will need to supply in addition a USB C angle adaptor to make the power cable fit.

Ive slightly altered this version to the one I printed - Ive added a small shim at the base of the SSD as it was too loose for my liking and Ive added some supports in the side section vents as when I printed it went awry there.

Apart from that its slightly oversized to aid venting and Ive gone with posts for mid supports and slots for the ends so pretty stable.
