4x 2.5" Hard Drive to 1x 5.25 Hard Drive

Just a basic 4x 2.5" (laptop) hard drive adapter to fit in a 5.25 (CD-Rom) slot. I added 2x 40mm fan slots to this, however I don't have my fans yet, so I haven't tested that part yet. The spacing allows for 15mm thick drives. I printed in PLA, and it seems fine, but I may reprint it in ABS or PETG if I find the drives are getting too hot.
