Bruce Rayne's put STLs on Thingiverse that let you 3D-print a nice looking case for Kay Koba's SP][SD v2 Smartport drive kit. Bruce made separate STL files for the 0.96" & 1.54" OLED displays, both of which are offered at Kero's Mac Mods (Japan).

🔴 UPDATE on Right Speaker DEFECT 🔴
My dealings with technic-lee show them to be an honest and friendly EBAY vendor who I highly recommend. These courteous folks responded promptly and very professionally to my mention of the Right speaker crackle defect. They resolved the speaker issue to my complete satisfaction. It was definitely my best transaction experience on EBAY to date. Regarding the Apple logos missing on the Service Parts, they offered this helpful information:
We wish Apple would put logos on their service parts but unfortunately they don’t. It would definitely help with consumers wanting to repair their own machines. We can only guess it’s because the parts are internal and only meant for authorized service providers to install. However, that may change soon as Apple has announced their Self Service Repair where they will start selling their parts directly to consumers.
The number on the box is the Apple part number. The part is made in a factory in China. Not sure if it’s Foxcon, where they produce the iPhone, or Flex, in Singapore, or some other factory. They are pretty tight-lipped about it and since they ship the parts from their warehouses in United States, we see no addresses or information to give us any clues. We aren’t even sure if the parts come in similar packaging in other countries. All the parts come in the same plain brown boxes or envelopes, with the Apple part number label and green tape.
