Mechanical Logic Gates - AND OR

I made these mechanical logic gates in FreeCAD to teach computer science basics to a younger group of students.

Printing recommendations: PETG (PLA springs wont last), no supports needed, AND gate pivot point will benefit from increase in perimeters for strength (see 3mf version modifier).

I am very much a FreeCAD beginner but this was a fun way to make something functional for learning and get over my fear of models with curved lines!

Lots of inspiration from other logic gate attempts and parts, but none of them quite had that compact ruggedness and fun for the younger crowd I was hoping to achieve:
