I doubt the school would be ready to fund heavyweights, so I'd probably get either ants, beetles, or feathers built, with feathers at a stretch. More than likely, this will be done over several weeks, maybe into next year, since the machines will be either 3D Printed or made using milling machines, or other facilities at my school. I have gotten the go ahead from the engineering teachers, after October half break it should be on tuesdays. If anyone is near or in Sheffield, feel free to drop in, and give a hand or look around, many people come in to take a look at our school. (By the way, I am a student, not a teacher)
