Giá đỡ HDD 3.5" cho thùng Cooler Master Elite 110

The Cooler Master Elite 110 Mini-ITX case is a decent inexpensive case. However it only fits 3x 3.5” HDD. This bracket fits 2x 3.5” HDD on the side for a total 4x 3.5” HDD. Perfect for a mini-ITX NAS build.

Print the main bracket in ABS or PET using 0.20 Normal profile. The bracket has 8 holes to attach to the case and 8 notches for two HDD. The 8 holes align with the 2.5” mounting holes on the Elite 110 case. The 8 notches are using SFF-8301 spacing and should work with any 3.5” HDD.

Pre-tap the 8 mounting holes in the bracket with the hex-head screws that came with the case. It’s a lot easier to do this before installing it into the case. You only want to go in a few turns to get the thread started then remove the screws and install into the case. Make sure the bracket doesn’t interfere with any rivets or plastic plugs.

IMPORTANT: the hex-head screws must NOT poke through the bracket. Make sure you use screws that are short to avoid this. Otherwise the screws could damage the electronics on the HDD.

Now attach 4x pan-head screws to the HDD through the printed collars. I used pan-heads with 7mm OD heads and 3.5mm shaft. The collars and pan-heads together form a “T-shape” which sits snugly in the notch, keeping the drives firmly in place even when shaken or held upside-down. Print the collars in ABS with 1 wall and 0.15 Optimal profile and Thin Wall Detection.

Now slip the HDD onto the bracket by aligning the 4 pan-heads with the 4 notches and push down firmly to lock into place. The collar should fit snugly in the notch, but not too tight so it needs excessive force. Give it a wiggle test to instil confidence before installing the rest of the PC components and cabling.
