Clip for round dry box

I'm storing filament in round storage boxes from Hobby Life https://www.amazon.de/-/en/21143/dp/B01C4DDQCE

They are perfect shape/size for filaments and they are stackable.

They do not form a great seal so I made these clips to improve the situation and to prevent moisture from getting in once closed.

I recommend you print the clips for each box with the filament that's inside the box, then it works also as great filament swatch :)

To improve the seal, I recommend printing this out of TPU https://www.printables.com/model/959820-round-dry-box-tpu-seal
