Toothpaste Tube Coupler (non threaded to threaded)

UPDATE: I made a smaller coupling and uploaded it. I found the original wasted too much paste with the large gap between the threads and the curve. Yet another toothpaste transfer device. I designed this one to transfer toothpaste from a tube with a snap lid (no threads) to a threaded tube. Just thread the coupler onto the threaded tube and push the non threaded tube onto the opposite end. Keep pressure on the non threaded tube so it seals well as you transfer the paste. My travel tube is a 52ml Colgate tube. I can't guarantee that the threads will work with all brands or sizes of tubes. The first time you thread the coupler on it will be tight, but after that it will be nice and smooth.
