FLEX HOSE COOLING

perfect fit upgraded. print female end up and enjoy.... the fit used to be bad when i tried it. i modified the female end to be bigger and more internally open. its an amazing fit now{fits itself} ...if it isnt a clean looking printlines, , use 94% flow

ps make sure you have a good blower with a 15x20 end to fit this blower box.
my other design is better flowing----see my latest design i just uploaded
