ratcheting toothpaste squeezer v4

thingiverse

As you tighten up the tube by turning the knob, this work is done by ratcheting. I used supports at areas where there's only a tiny bit available. After assembly, the ratcheting part works well due to a little support under the ratcheting levers. You can try printing without supports, but I haven't attempted it yet. The turning direction indicator is located on the opposite end of the turning rod. I recommend using very high infill for the area between the roller knob and the end to make it as strong as possible and prevent it from breaking too soon. A frame with a slot was added due to request, but personally, I don't like it because it's more work.
