 So Fidget Spinners being the latest craze, we decided that we wanted to go and show all the design process taking it through from prototype to final product. So first step is to put all your measurements and designs into the 3D software, place all those components together into one part, then send it either to the laser cutter or the 3D printer to make the prototype, and then actually physically put the parts together to make sure that they all fit. So while Fidget Spinners are something you can mindlessly do with your hands while not paying attention, you have to put a lot of attention to detail and actually getting the design right so you get something that's useful at the end. So if students have an idea for a product, the only limitation is the size of the machine. So what I love about engineering is the fact that you can think about something, create it, prototype it and get it in your hands within weeks these days.
