car window ventilation

thingiverse

DISCRIPTION: This device should provide airflow into the car. I designed it to be able to sleep in the car and keep rain and mosquitos out, while not suffocating. DISCLAIMER: Fist of all, if you can build it from metal as to be seen in the template, is probably way easier and less expansive. I had time and needed a project. As I have no tools to modify metal but a 3d Printer I hereby present my model in case somebody out there also likes life rather complicated than simple. MATERIAL: I worked with PETG (grey) for the main parts and TPU (blue) for the sealing in between the parts. These sealing also have different inclinations as no window is a perfect square. You can probably also just glue them instead of using TPU and see how much of the inclined sealings you need for the perfect shape for your car Window COSTS: Each of the main pieces uses around 140g of filament. With my PETG I had about 3,5 Euros of cost each, so in total probably around 18-20 bucks for the whole thing (including the sides). For me, I needed 4 pieces of the main PRINTING: For the main piece (the square with the ventilation slots) I added a mosquito. This was done by adding a volume part in the slicer and printing this without top and bot permieters and setting the infill to grid 50%. This leaves you with a mesh of around 1.5mm squares. PS: The hole in the thicker side piece is if you need an electrical cable to go through. If not needed the small cape can be slid onto the cable shaft.
