3D model description

This was designed to replace an inline booster fan i purchased. I found the fan was far too noisy for my office and wanted a more silent solution that didnt break the bank.
It uses 4 x 120mm 12VDC CPU fans.
The CFM is close the booster fan i replaced but the pressure wasnt as strong. Seems to ventilate my resin printer fairly decently, while being much quieter.

For Hardware:
4 : 120mm CPU Fans
1: 12VDC power supply (make sure to calculate the power required for the 4 fans).
16 : 8-32x1.5" machine screws
16 : 8-32 nuts with washers.
The "Nut Gasket" models have a recessed cutout for the nut so you should only need a screw driver to install everything
Once all the pieces are together i used duct tape for all the seems and gaps.

3D printing settings

0.6 nozzle
0.2 layer
No supports (can get a little messy at the higher angles, but i didnt care). i also printed it fairly fast.
