The gear version is printed as one item.? Theoretically the gears have a tiny bit of clearance.? With shrinkage they had more than a tiny bit.? I don't think it's supposed to be able to come apart.? I don't normally print 0.15mm.? I have done some 0.1mm layers but normally run 0.3mm or 0.4mm with 20% infill.?
?
I suppose one could try 0.1mm or 0.2mm and maybe less infill or maybe 100% infill.? But this particular one took 3 hours.? Now that I've played with it I have issues with the design.? And the moment you add a piece with 3 pins to hold the gears at a fixed diameter the gears turn on the pins, you need lubrication and at this point might as well use the 3 or 4 bearing technique.
?
Anyway, it's not worth spending money on tubing to try and make it work.

I'd go along with it requiring some sort of carrier ... nice idea though.
3mm ID tube and the original motor will give you quite a respectable flow.? May need to speed control the motor as you can't throttle a peristaltic pump.? I got squirted with oil when a pipe blew off?whilst testing the original motor and a 1mm ID drip tube.
