Dispenser cup with detachable spout for hydroponic tower

The original design has the hose attached to the top dispenser cup in such a way that any maintenance to the hydro tower can mean that the hose needs to be fed through multiple sections from the bottoms up, and as a result the entire tower needs to be disassembled. That's a hassle.

Instead, this design separates the spout from the dispenser cup, and it's small enough so that it can be fed through the 20mm holes of any of the tower segments. The spout and tubing similarly is inserted in the the dispenser cup, where it is held in place with a simple plastic key that slides through the spout and settles into a groove in the dispenser cup.

Want to add/remove/replace a section at the top? No problem, just remove the locking tab, feed the hose through the section, do what you need to do, and reposition the spout and tab.

The sample cup fits around the spout, and collects nutrient solution, so when you need to measure EC or pH, you can simply drop your probe in the cup and get the readings. The cup needs to print with supports.

Printed in PETG, no supports needed for the tab and the spout.

split up the cup and the spout, then modified from there, in order to make it more modular.
