A version of the lock icon has been added, which solves the problem that the text may be unclear.
Description:
Protect your butane gas canister head.
Tighten clockwise, loosen counterclockwise.
Tested with BEIYUE 220g gas canister, other brand not tested, should be the same size theoretically.
Print in place.
PETG suggested.
3 version available, 1 with text orientation, 1 with icon, 1 without.
If you need to print a two-color version with text/icons, it is recommended to use strong contrasting colors, otherwise the text/icons may not be obvious.
A two-color version with text/icons can be printed without AMS. After slicing, add pauses on the 3rd and 7th layers and manually change materials.
