Vòi điều chỉnh nước và gas cho bình nóng lạnh Cointra

Regulator control for COINTRA brand gas water heater, it broke a while ago and I decided to try my luck designing it and in the end it turned out quite well. It fits perfectly and does its job. Printed in PLA, although it can be printed in PETG, it does not need supports. In the first photo you can see the two controls, the one on the left is the original and the one on the right is the one I designed and printed. We look almost identical except for painting the black stripe.
