Aquaponics Topper (Widemouth Mason Jar) v9

thingiverse

I designed this topper specifically to elevate a small Solo cup above the jar, which is filled with water and a pair of tiny fish swimming inside. A carefully placed hole allows for an air line to be inserted, providing essential oxygen that both plants and fish will greatly appreciate. An additional hole is incorporated for effortless feeding or to serve as a viewing window into the underwater world below.
