Used https://www.thingiverse.com/thing:454702 to get a working pump and added holes to make it compatible with lego technic. I've been using it with 6mm silicone aquarium tubing to pump small amounts of citric acid into a baking soda solution at regular intervals to produce C02 in an aquarium.

There are versions with different squish ratios (parameter from the parametric peristaltic): 0.3 squishes the tubing less and is easier to turn 0.4 squishes the tubing more and is harder to turn. Without a gear reduction, this one barely works, try 0.3 first.
