I made a NAS in an old PC case. Couldn't find the original HDD rack, I removed it years ago and probably threw it away or something, so I had to print one.
After some looking I found these files which did what I needed, and edited them a bit. Decided to share them here.

Since I needed to print 6 of these, I wanted to reduce print time and material usage as much as possible.
I removed a lot of unnecessary geometry from the caddy, which for me resulted in a significant reduction in material (about a 30% reduction) and 1 less hour of print time for each print which saved me 6 hours in total. The caddy needs supports for buildplate only for the slides to print correctly. You can print them as overhangs too but they might come out a bit ugly. It's really just a few mm of Z height so I suggest using supports.
