About this 3D model

My leaf blower is great to blow leafs but not ideal to be used as an air blower dryer for the car, that's why I made my own. I've design 2 versions, version 1 is shorter (15cm) than the original but with same size at the end. Version 2 is the shortest (12,5cm) and with a small tip in the end to increase the speed at the air exits but has a shorter area. Feel free to remix it.
