Remixed the "Best toolless SSD mount 2.5 to 3.5 adapter" by elmantec to accept 2 SSD's since it's still less than the height of a 3.5" hard drive.

One of my SSD's didn't fit perfectly (just a tad long plus very square corners) so it's worth measuring your SSD's before you print. Since mine was already printed, I just dremeled/filed off a bit of the end tab.

I also in retrospect would've added holes for screwing into the hard drive bay since the toolless "buttons" don't line up where I needed them. I ended up drilling and tapping holes. So you also might want to verify that those "buttons" are where you want them to be. I liked the toolless idea but I should've checked that it would work for me!
