This is another design for an air intake snorkel, without considering pipe length or any noise cancelling function. Its a simple design for maximum air intake.
I have not printed or tested this design, it was just created for fun.
The original one was pointing straight. As you lower the fuel tank, you might notice that there is not much space above the intake snorkel, there is a second variant (v5-low) which is bent more downwards considering this.
It is designed to be printed with flexible filament (TPU) and can't be mounted when using PLA or other stiff materials. The inner flap is smaller than the outer one so it is easier to push inside the airbox than the original intake hose. There is no need to disassemble the airbox.
