51x15mm blower model, Orion Fans # ODB5115

This is a 3D model of an Orion Fans ODB5115 centrifugal blower..
It is not intended for printing, though it should be printable.
The purpose of the model is to help with the design of fanduct-type things.

I'm getting ready to design the next step up from my Z-19 project. Check my designs, if you don't know what I'm talking about.

The original fan is a tiny blower, 40x10mm if I remember correctly.
The 50x15 is a popular format for model cooling upgrades.
This one I've selected is 51x15,
