Modular 3.5" HDD Rack
Description
Credit for the original models: https://www.printables.com/model/40826-35-generic-hdd-caddy https://www.printables.com/en/model/383555-hdd-expandable-rack-v1 I'm making a NAS in an old pc case. The original HDD rack was removed and likely disposed of, so I had to print one. I found these files which essentially did exactly what I needed, and edited them a bit. 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 1/3rd less) and 1 less hour of print time for each, saving me 6 hours in total. For the stackable rack, everything was mostly OK. I removed the mounting pins on the side as I found using them would make the thing more wobbly than I would have wanted. and needed supports to print correctly. Instead I opted to just glue each rack module together with the next. other than that I added a few chamfers, all together they make the model printable with no supports to save time and material. I'm also including my mounting system although that's very specific for my use case and you'll most likely just have to come up with your own. In my case it was made to offset the whole assembly up of 15mm to clear the edge of the case, and mounts to some pre-existing holes in the bottom of the case through m3 screws and heat-set inserts.
