There are a number of 2.5" to 3.5" hard drive brackets on thingiverse, but ALL the other ones don't seem to be for hotswap server bays with drive caddies (because they don't mount the SSD in the required position).That may be because you can just screw your SSD into the corner of the caddy with two screws, but if you want it to be a tiny bit more secure, just print this out and screw it to the SSD drive (and then to the caddy).Print and use!
