Usage
This roller clamp can be used on elastic tubing ranging from only a few millimeters up to 16 mm in diameter.
The main difference between the models is the wall thickness of the tubing:
The 12 mm model works for a wall thickness of 1.5 mm.
The 16 mm model works for a wall thickness of 2.0 mm.
Other thicknesses may lead to dripping or impeded operation. Feel free to adjust the wheel diameter, or better the height of the side walls, to fit any specific tubing dimensions that you have.
Printing and assembly
I suggest PETG, but other materials work just as well. Depending on your printer's tolerances, the crossbraces might have to be glued in place, so they don't come loose during operation.
The same goes for the axle, but it is usually held in place due to the geometry.
The clamp can be assembled around already installed tubing without access to either of the ends of the tube.
You can adjust the direction of operation by reversing the assembly of the mechanism. The arrows in the wheel help you keep track of which way is open and which way is close.
I found that a little bit of vaseline or other lubricant on the axle pegs makes the operation much smoother.
