After a long time I think I finally came up with a good design that has probably the smallest form factor
it uses this:
m.2 nvme to usb-c adapter
It uses no screws
It is print in place
Assembly Guide
To put it together just follow these steps:
-
Remove the USB-A Port
The adapter has a USB-A plug on the other end, gently remove it. You won’t need it for this case. -
Smooth the Edges
The fit is tight by design. Lightly file or sand the back end of the adapter where the USB-A plug was to make it slide in more easily. -
Clean the USB-C Port Opening
Check the opening where the USB-C port goes. If there’s any leftover filament from printing, clean it up with a small knife or file. -
Insert the Adapter
Line up the USB-C port with the hole in the case and press it through. It should click into place and sit flush. You might need to press firmly—it’s a snug fit. -
Add the top cover
Now just add the top cover (optional)
