Eh, kind of double-posting below - as I necro-posted to a 2-year old thread recently. But, I thought this information was too valuable to hide down deep in a page two somewhere.
For those of you with 3D printers that want to mount 2.5" drives into your chassis, even non-Supermicro chassis, here are a few options.
This one below is much the only option if you have the big 15mm height SAS drives, like the STEC s840:

This one lets you use the older SC trays without the 2.5" mounting holes (especially if you use a few dabs of hot-glue or thin double-sided tape). Mainly because it has such a large shelf for the SSD to rest on (the pic is upside down, remember).

And this one doesn't use any screws to mount it into a sled because it has little nubs that normally go where the 3.5" screws go (to save you 4 screws!). You can try just 2 normal generic screws might work fine with the older SC trays that do not have the 2.5" holes:

I suggest printing in PETG for the higher-temps, just in case the SSD gets too warm (PETG can handle up to 80C, whereas PLA can only go to 55C). But PLA could work fine, just might get brittle if you run high-ish temps in your workhorse.
Also, if you're interested, I have more chassis/server-related 3D models I've printed/bookmarked (most are not SC specific):

There are a few more variants of SC 2.5" drive adapters there, including one if you wanted more airflow.
There's also a dual-2.5" adapter you can print and place next to your PSUs.

Simple 2.5
Originally built for Supermicro hotswap trays using Apexio's design. After printing and thinking about it decided a more generic version could be made that would also work on Chenbro and Norco cases.Have not made these for older Supermicro trays that don't have 2.5
