Detachable connector used to replace a broken side release buckle on a dry bag with 3/4" webbing. The two pieces of the buckle are the same. Press together to close, twist or slide apart to open.
This design is not as secure as a standard buckle, but is much smaller. There are two versions, one for printing with ABS, another for printing with PET.
I'm not sure this part will work as-is on other printers, the tolerances need to be very precise for it to hold securely.
