save yourself $100 on a 12 bay shelf

designed to replace caddy model 72CWN
this is not for regular servers, only compellent disk shelves

fair warning I made this remix through trial and error and do not have an original caddy for reference
seems to work fine though, see reference picture
the left side rail's front piece is about half a mm too high, but the disk is actually level, it's just a cosmetic issue

front piece intentionally not included, it probably won't fit well with my changes and it's pointless to block airflow

I'm using an SC200, should be fine for other compellent shelves
the MD1200 and similar shelves should work with standard caddies

no special notes, print without supports, I printed mine laying down with the most surface area touching the bed rather than standing up

also I have to say I'm shocked there aren't already models for this type of caddy anywhere.

side notes for anyone not familiar with these disk shelves, you can make them very quiet via serial console, just need three male->female dupont jumpers and a USB to rs232 serial adapter, connect with putty or your client of choice, no password or login needed

the fans (which only reside in the PSUs) can be replaced with noctuas to reduce noise further
