Hobby 3D CNC technology already exists, and several free 3D software design tools are currently available, so it seems that a lure-making machine could be plausible for people wanting to pursue making their own baits in an automated fashion. The cost of the associated table-top equipment; however, might indeed be twice the originally posted number..
If there were such a machine, and it were capable of CNCing only balsa wood, how many do you think could be sold at a $2,800 price point?
