This is a complex, multi file model with precise tolerances.
Make sure your printer is in good working order, tolerances proceed
all the way down to .20mm working gaps. Use High Quality Filament.
Printed at .20 layer height on a .4 nozzle.
You will also need to buy a specific spring Which is a 3/4in. (L) 1/4 OD x.028 Wire Gauge, Extension spring I picked mine up from ACE hardware.
This is also the same spring.

You will also need roughly 6 and 1/2 inches of 1/4" Internal Diameter 3/8" Outside Diameter Latex Tubing. It has to be latex to allow the water to stop flowing,
I got a foot of it cut from Ace Hardware as well. I advise going to purchase at a hardware store because then you wont have to get multiple feet. But can also be purchased online.
Assembly is in a video link. Feel free to email with any questions, or contact me on social media.
