Aerogarden "spacer" cap for flexible filament

thingiverse

Use this to block off empty spaces in your Aerogarden to keep light from getting into the water and promoting algae growth. These must be printed with a flexible filament, such as TPU. If you print them using a rigid filament such as PLA, PETG, or ABS, they won't work. These are much better than the rigid ones I posted a long time ago because they don't easily get knocked out of place. They take very little force to install or remove, but they will not fall out if you blow on them or if you take the grow deck out of your Aerogarden and run water over it or turn it sideways. Use the darkest color filament you have, preferably black, to help really block out any light from getting through.
