Remix of Dubry's design. Adds 10mm of additional clearance between the fan and the Pi, raising the fan outside the main body of the case. This adds more space for heatsinks and any internal wires you might need to run.
I'm including the STEP file, but the model is based on Dubry's STL (converted to a solid), so it will be a bit more difficult to work with.
The author remixed this model.
