Quick Release Connector

The mechanism uses a standard spring from a pen, cut in half. The pin locks into the main part and can only be released upon pressing the sliding part and then unlocking the pin. Uses 4 screws to put the plate in place and 2 screws to attach the pin. The main body should be attached to something, which we will connect with glue, you could also easily design holes for screws though.

Printing without brim to make sure it all fits, otherwise make sure to get rid of the extra edges as this could interefere. Make sure the spring is not too long and therefore too stiff.

Good luck with printing.
