HDD tool-less lock

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.

Infill: 

40%

Filament: N/A PLA N/A

Notes:

Should be printed in the provided orientation to avoid layer weaknesses in the pins.

Must be printed with supports touching buildplate only, but no supports internally (they will freeze the lock).

If using Cura, Print Thin Walls must be enabled. The print-in-place lock mechanism has very thin built-in supports.

If using Cura, normal supports with Support Placement: Touching Buildplate (not "Everywhere") will work. Normal supports work best, 1 wall for a better surface (but harder to remove).

If using tree supports, adjust:

Tree Support Branch Distance: 0.5mm Support X/Y Distance: 0.3mm

Failure to adjust these distances with tree supports should still produce a functional part, but the turning circle might not be a circle.

Depending on your bed adhesion, a brim or raft might be required, as bed contact is minimal.
