About this 3D model

Ever had a small piece of filament broken in your PTFE bowden tube? I designed this adapter for a vacuum to remove small broken off pieces of filament with suction. Just detach on end of the tube and put it on the suction part. Works great for small pieces, but bigger pieces are harder to get out. Fits vacuum cleaners with dimension of 31,5mm The part prints without support. Please let me know if you have ideas for making it even better.
