All parts used in this project were recycled from discarded computers except for the green plastic bracket,
which was 3D printed.
The cooling fan from a Dell Optiplex was used because of the power connecter.
The initial design was done using
Sketchup.

The final part, a simplified design was modeled for printing using
TinkerCad.
Sketchup has an STL plug-in but was not used for this project.
The plastic bracket was printed on a 3D printer.
The size 3 3/4" x 3 3/4" x 1" tall.
A heatsink was salvaged from a discarded computer.
The 3D printed part was fitted to the heatsink.
The fan was attached with screws.
