X carve files to make robotic arm

Does anyone know where I could find files to make a robotic arm out of plywood then assemble. I need to make for school fair

Are you looking for something simple like up down? If so you could find the plans for one of those lamps, pretty sure someone here made one and posted…


Something like this?

Thank you but looking for something with more than 2 axis.

Thanks this will come in helpful when designing the final product!

Thanks this is what I was looking for
