Smaller casing for a Samsung PM883 SSD

Needed a smaller drive so I could fit an SSD and an M.2 in my laptop.    I've added the M.2 riser for a dell e5570 and the holder I remixed (https://www.thingiverse.com/thing:5161985) in case anyone else needs them (very specific use case I know).    Updated the measurements of the M.2 riser so it fits without being wonky (see pic with green parts)
