Motorcycle jacket ventilation, breather

I have a leather jacket which doesn't even have zipper ventilation but I decided to be cool about it and I made this system. I used the same printed parts to draw and cut the jacket. It can be mounted anywhere on the jacket but check if it doesn't bother you before. It takes M3 screws of about 10mm in length. The holes and the lift it has underneath is supposed to push the air throughout the jacket. You could glue a piece of sponge on the inside of the top part to avoid high speeding bugs entering and eventually leave bruises.

Update: I added a new version with a better design both for looks as for the airflow. Should be placed on each side so the air goes towards your arms. Going from higher to lower volume will increase air speed, drop the pressure and get a more refreshing feeling. I applied the same principle as for the one for the back of the jacked (see my other design).

Be cool and ride safe!
