These couplers are designed for RC-model airplanes with pneumatic landing gears as connection between the fuselage and the wings. The connectors are standard parts from LinkTech with a bayonet coupling that has to be removed before the male and the female parts are pressed fit into the printed parts. To detach the bayonet couplings from the LinkTech parts I added the tool ‘Ausdrueckwerkzeug_V2’. The couplers are designed for 4 mm thick ribs.
I use the couplers with 3x2 mm PUN tube but secure it with CA glue to the LinkTech connectors.
