A new Prusa I3 Geeetech 70 mm customizable cooling fan. With switch

thingiverse

I wanted to redo the fan with a measurement of 70 mm because I realized that the 40 mm were not sufficient. With this, the final results needed are much better. Sorry if my English is bad and if my source program OpenSCAD is worse - I'm still learning. I decided to add a switch since the Aluminium Prusa I3 Geeetec with Sanguinololu cannot handle ventilation on its own. This is super handy when printing in ABS, and you don't need to disconnect the cable. I redesigned the ventilation system with a 70 mm fan because I checked that a larger airflow improves the print quality even more. I added an interrupter so it's much easier to exclude the ventilation without unplugging the cable. My printer with Sanguinololu can't manage ventilation regulation on its own.
