iPad/Tablet - cooling case

Since modelling software constantly turned my ipad into a heater, I designed a simple but highly effective cooling case.It's not perfect, but it works.It is sized for the 12,1" ipad, but can simply be resized to fit any tablet. I don't know if any buttons will be covered, but I removed most of the frame so there's room for other configurations.I use 2 38x38x8 mm 5volt fans. The prototype had a 120mm fan, but that was complete overkill.The casing for the fans can be printed separately and is glued to the back so it should work just fine with any size adjustment.
