Toothpaste Squeezer
A flat slide-style squeezer for getting the last bit out of a toothpaste tube. Thread the flattened end of the tube through the slot and push the squeezer toward the cap. The slot has a 0.8 mm 45-degree chamfer on both faces so it does not cut the tube, and an optional hole lets you hang it up. The default size is 82 x 22 x 6 mm with a 60 x 2.6 mm slot. Print it flat with no supports; if the slot comes out too tight, raise the slot width in 0.2 mm steps. Adjustable parameters: slot length, slot width, body thickness, body width and the hanging hole.
