These are one piece tube squeezers; one for toothpaste size tubes and a smaller one for smaller tubes such as paint or anti-biotic ointment.
They are designed for easy printing as one piece. the slotted part is faceted so that the overhangs do not exceed 45 degrees for a good print.
I have also included an stl file of four small squeezers for your conenience.
