Print standing up on its side and print in place (no need to separate the parts). The tolerance between moving parts is .3mm and that has worked out just fine on my Ender 3 V2.

Do print with supports but no need to support the pictures on the sides.

Since I prefer this print orientation (for rigidity of the hinge) I coloured the black parts of the sign after the print was done (using a permanent marker).

This is the first time I have really designed something that works with Fusion360. I'd be very happy if you let me know how I did and leave a like, comment or remix or whatever else you can do on this platform :)
