Filling Module Hole Plug for Modular Hydroponic Tower

This thing contains 3 different plug options:

1. Flat plug - This flat plug is meant to plug the entire opening where a cable does not exit.

2. Plug with rectangle Hole - This plug is meant for anyone who has a thin cable exiting the system. It will fit a cable that is no larger than 4.5 mm X 7 mm

3. Plug with round hole - For those who have a pump with a round cable, this one is for you. This plug will fit any cable that is no larger than 8.25 mm diameter.

These covers / plugs are meant to plug the 2 holes on the side of @boundarycondition's Filling Module.

At the top of the second plug I created a slight gutter that keeps water from falling through the small hole by div
