Extension for handheld vacuum

Extension for Ryobi handheld vacuum cleaner and others with the same diameter. I was annoyed when I couldn't get into all the nooks and crannies, so I figured I'd make a simple print to do something about it. The tube is 160mm long, 31mm outer at one end and 36 mm outer at the other end. The vacuum I use is the Ryobi RHV18. This is very easily made in OpenSCAD, and is my first model. I've tested with two types of PLA and it's worked fine.
