HDD tool-less lock
thingiverse
Made to fit the 3.5" HDD bays in a Cooler Master N300 case. Might fit other cases. The spacing of the HDD screw hole pins should be standard, but the locking mechanism might change. Pay attention to the print settings, since the locking mechanism can be difficult to print correctly. Use the 60mm file if your case uses the rear two screw holes on the HDD (e.g. N300). Use the 41.6mm file if your case uses the forward two screw holes. If your HDD is missing the middle hole (larger capacities), snap the extra pin off.
