Microsoft Surface cooler fan

My Surface has no internal fan, therefore it often overheats. For the last years I places a small PC fan behind my laptop. Now I designed this holder which keeps the fan connected to the Laptop. For power, I just connected the wires of the fan to an old USB Kabel. With 5V from the Laptop, the fan runs quietly but keeps the laptop cool enough. The holder can be simply cliped on and off if needed. I used PETG as support material, but normal support should be fine as well. Needs 2 screws to hold the fan in place.
