Vacuum nozzle 31 mm inside diameter

thingiverse

My first done in sketchup, I wanted a nozzle to clean my car. This is my first stl made in sketchup, so the design is really bad, it is basically a 15 mm tall cylinder that is connected to a rectangle by some really sloppy triangles . My goal was to have really thick walls and a sturdy nozzle that wouldn't break when using and also which would print ok even on a very bad calibrated printer . Any remixes that improve the printing time are welcome !
