My Wife told Me to use My printer for something useful, so I designet it for Her.
Idea is based on the one from henryk, but with slight modifications.
I made 2 versions, both of them fits a 5 mm bamboo rod, the bigger opening is 10mm, so does not harm the plants.
Printed from PLA (Form Futura rPLA, Venom green).
The author remixed this model.
