My daughter (7) made a robot out of cardboard and asked me whether we could make one on the CNC. I told her to draw some plans and explained to her how to “unfold” 3D objects using a six-sided die.
She came up with these plans, which we then put into AutoCAD (her drawing the squares (took ages…), me doing the rest):
Okay, you win! That is the best project I have ever seen around here. You just taught them the entire process of idea to actual thing. Man, I am smiling ear to ear with this one!!! You deserve a trophy.
