Dell 4 HDD OptiCage

thingiverse

Here comes yet another imaginative project to add to my obsession with piling hard drives into things that were never meant to hold them. This is a bolt-in upgrade designed for many Dell mini tower chassis and uses the standard Dell HDD caddies. It requires drilling three bottom and five front rivets, which is very easy to do. Once this is done, it reuses the bottom three and two larger holes during re-mounting. Due to inconsistencies in chassis manufacturing, the holes might not line up perfectly, but they are close enough. This cage will work on several Dell models: Dell Precision T1650, T1700, 3620, 3420 Dell Optiplex 390, 790, 990, 3010, 3020, 7010, 7020, 9010, 9020 Tower I will post a video and update this project later once the build is complete to show how it was installed. In conclusion, I used a Robo R2 printer, which is decent. A test print at 70mm/s showed some issues - the corners bulged around the keyway that the HDD caddy slides into, making it very tight. Slowing down the speed fixed the problem, and the caddies fit perfectly. However, there's a catch: when printing at 45mm/s with a height of .2, it took an astonishing 32 hours!
