Pipe Fan for Air Exhaust upgrade for enclosure

A Pipe Fan Concept for a planned air exhaust system for my enclosure. Should fit for 42mm tubes. 

The fan fits for standard 1$ DC 3-6V Motors (see picture of motor for dimensions). However the clamp mechanism is quite universal. Important is , that the motor is centered correctly - as it is holding the fan. the important dimension is the width of the motor between the clamps in my case 16mm.

For wiring drill holes in Cover part - glue everything for air tightening. Soldering is required for this project. 

For fixing the tubes use tape and glue. Maybe you have to add a simple adapter if your tube diameter is smaller.
