Yottamaster MS5-T3 Thunderbolt 3 Dock fan upgrade

Yottamaster MS5-T3 Thunderbolt 3 Dock is overall very good Thunderbolt docking station, and having slots for NVME and SATA M.2 drives distinguishes it from other solutions. But it has a major flow, a laud fan, 5V 4010 blower.

This base replaces this fan with 2x 7014 fans, which provides better cooling, and makes it very quiet (depends on the fan, the ones I used were not very quiet, but running them at 2.4V - originally 5v - made them quiet enough).

I am not expecting many people needing this, please let me know if you are interested in making one. I can provide more details.

Required parts:

• 2 x 7014 5V fan (I used fans from a laptop cooling pad, which also donated the metal mesh)
• 8x M5 screw for mounting fans (I used 4, and also used double sided foam tape to help with vibrations)
• DC-DC Step down voltage regulator (a module like this provided a quieter solution compared to PWM fan controllers, small size also an advantage)
• M3 bolts, 4x 10~12mm for fan shroud, 4x 6mm for bottom plate
• Metal mesh looks nice, also possible to 3d print
• JST PH 2.0mm Pitch 2-pin male connector for receiving 5V power from the dock
• Cable, connector etc for electronics

Print settings:

• Layer height: 0.2mm 
• Material: PLA
• Brim: recommended for “Base upper”, other parts should be ok

Notes:

• The aim was not changing the design a lot, and make it easy to revert the change if needed. Designing a new case with fan mounted on top of TB3 card which generates the most heat will probably be more efficient, and also make overall size smaller.
• Design has mounting place for base plate of the original case. This makes it easier to find the parts if change is reverted to the original, and also provides some weight at the bottom, lowering center of gravity.
• Fans are aligned to generate positive air pressure, which will force hot air to exit from the existing vents on the sides of the dock.
