This is a small case replacement for SSDs, since their internal board usually is smaller than 2.5' original case. I used this to make a small 4 SSD NAS, using a 3D printed ITX case, but you can use it for many other applications that have space limitations.

This model fits a XRayDisk (chinese) SSD board, and I think most chinese SSDs will fit since they usually have same boards. Netac has a smaller board than this and although you can use this case with it, I'll make a even smaller version for it in the near future.

Printing is simple, use your printer default PLA settings and you will be fine (no supports/rafts needed).

Assembly is also simple, no screws needed, just put the board inside aligned with the pins and fit/lock the cover.
