The indicator for the gas valve helps to visually determine whether the cylinder is open and to close it if necessary, since it is necessary to walk around and manually tighten the cylinders after working with them if they were not properly closed.
Three inserts have been designed for different types of valves; the model has been tested on real cylinders.



The device is equipped with:
magnetic closers,
reinforced stops,
latch,
grip‑friendly frame for opening a stuck valve.
The model requires:
8 round magnets 5x2,
5 M3 bushings (I used M3x4x4.2),
5 countersunk head screws M3 (DIN 7991 M3x8).

The lengths may vary slightly.
Printing recommendations:
You can print from whatever you like, but I recommend printing the insert for the vent from TPU.
Perimeters: from 2-3
Infill: from 20%
I’d be glad to see your makes and any suggestions for improvement :)
