Google Fan Filter Challenge

thingiverse

This is my submission for the Google Fan Filter Challenge at the Midwest RepRap Festival. It's specifically designed to hold a filter cut to the exact size of the fan at a 45 degree angle to the fan itself, making it simple to insert and remove. The design also features only three mount points, allowing one side to remain open for easy insertion. If the fan is mounted squarely, the filter will be inserted at an angle. This model can be easily customized via the customizer if your fans are a different size or require more depth for filters. I've included the default values as 120.stl. To print this design, use approximately 20% infill with your preferred infill type, but make sure to avoid solid layers at all costs. This will create a grid-like surface that allows air to move through. For the 120mm size, I used four perimeters.
