Dual 2.5" sled for 3.5" devices

I am building up a storage server for my classroom, and have a bunch of old spare parts.  I needed something to convert from 3.5" drive bays to 2.5" drive bays, but.. supporting two.  This is what I came up with.

Note there are a bunch of mounting holes, each one fits what I have, you may need to make the holes bigger (use a drill).

I would print it in PETG.  I uploaded .3mf file for PLA, but this was for the test piece.

You will need supports for the ledge that holds the top drive in place.
