@Sebastian_80249 Hi Sebastian, I bought the small chain in Hardware store (Bauhaus). With help of pliers I disasmbled one chain link and assembled it back within the hearth.
Thank you! First set is printed and ready to find new owners. I just hang them near a subway station – and nearly forget to make a photo. (edited)
@Greenmagenta Thank you 🙂 Looks great!
@MartinCrow 🙂 you are welcome! It should motivate to help to Ukraine.
