Klammer für Pflanzschild aus Einsstiel / Clamp for clay pots and wooden signs

thingiverse

My problem: In my propagation boxes there's such a humid climate that all my wooden propagation signs are moldy. I try to avoid plastic in the garden as far as possible and have switched to wooden signs and clay pots. But since the wooden signs go moldy when I put them into the soil, I've developed clamps so I can attach them outside the pot. One clamp is made for small growing pots with a diameter of 8 cm and wooden signs with a width of 10 mm and a thickness of 3 mm. I printed it using wood-PLA that contains at least 30% bamboo.
