this is a multipupose sign thing. you just insert the sign part you want, into the base part and flip up to view. i use the fish sign to show that the fish have been fed, when it is up. and not fed when it is down. you can use it for anything you like. signs included are an angelfish, moana , dory , and tinkerbell.. the base is printable in one piece.
the base can be remixed into your sign designs. or whatever you need to flip. included is a .step file so you can make your own sign.
