Four different models, two are thicker at the shaft for durability, and two are thinner and needs less filament. Two has a pointy end, which can be used to scrape dirt off with, and two has a rounded end.
The one I'm showing printed is the "Thick Pointy"
Can be scaled to fit different vacuum hose ends.
Made by me in TinkerCad.
