LED Light Shade for mounting on PC Heatsinks (parametric / Freecad)

I made this light shade so I would not get blinded by a 7W LED.
The disign is straight forward, I used the base area of an old mainboard heatsink plus its mounting holes to define the outline. From there I just extruded a funnel so the light would only shine down and not in my eye. There is a 10x2,5mm opening on the side to let the cables through.

I'm providing the Freecad file so you can change the model by your desire, it also helps retracing the steps of how I made it.
