I designed this tooth paste squeezer as I realized the all other are dependent on scrolling the tube upon itself, this one squeezes it between two barrels. The design has a 51 mm barrel, suitable for most small and medium size toothpaste tubes in the market., you need to print 2 pieces of the barrel and 4 pieces of the bracket, for assembly just put 2 brackets opposing each other, on each end and superglue them to each other, avoid dropping super glue on the axle for obvious reasons, I recommend you keep turning them for about 3 minutes after applying super glue. It is made by PETG but PLA will work finely as well. use supports for printing the cylinders and print them Horizontally to increase strength.
