A simple camera with a pushable button and rotating lenses, great for kids play.

All parts can be 3d printed, including the spring, but for best performance I'd recommend using a metal spring (I've used a 15mm diameter by 30mm tall like this). If printing the spring, try using something like PETG as PLA can be too brittle and might cause the spring to break.

Assembly instructions:

• Place the back part of the model on a flat surface;
• Place the spring on the button cavity;
• Place the button immediately above the spring;
• Slide the lenses through the front part;
• Snap fit the front to the back using the guiding pins;
• Have Fun!
