A plastic housing with a twist lock to protect your seed, 3D-printed from biodegradable PLA.
The sealed polymer housing provides protection from moisture (delaying corrosion). This is particularly useful if low grade stainless steel washers are used. It is best to use high grade 316L stainless steel.
The capsule has thread features cut from the inner face which engage with thread sections on the cap. A short sharp twist of the cap pulls the cap closed, bumping the rotary lock pips into the vertical slots in the capsule. The result is a sealed capsule that can’t be easily dissembled without causing permanent (obvious) damage.
