That is the simple solution, yes. But less "Fun", especially for a kid. My thinking is more along the lines of an automated Dog Tag inscriber that you might find in the entrance of a big store like Fred Meyer or Krogers or whatever it is wherever you live. As a poor example, but more or less similar, except that I, as the storefront owner, have to load the plate or keychain or vanity plate or whatever the product is then pull it out once it's done with the customers design.
In this scenario I'm not a big production shop, I'm a storefront with odds and ends who has a mostly hobby CNC in a shop in the garage out back and the only time I can get to that shop to do any CNC work is after I have closed the storefront, since it's just me watching and running everything. If I build my well-sealed, dust free-ish and mostly soundproof interactive CNC "box" as described above in a corner of my storefront with a VERY dummied down Vcarve interface to mostly let the customer be in charge of designing this thing, well, it is something that isn't found anywhere else around town and will hopefully drive some degree of traffic in my touristy area. That's the idea - let the customer be in charge of their very limited experience and minimal need for me - that way they don't have to feel pressured, it's an oddity, that kitsch, that degree of "Fun" (for lack of a better word) that gives an edge and a market. A small market, but for a storefront every penny counts. And no, I have no idea what the ROI is, but no one does with a new idea. At least I think it's new in the CNC market, but I could be wrong (though my limited research turned up nothing like this).
Yes, to some it sounds stupid, I'm sure. But no more stupid than those crane machines in the lobbies of big stores that people occassionaly cram money into to try and catch a stuffed toy for no other reason than they can and it exists. But there would be no "Fun" factor if you just walked up to the crane machine and asked some guy standing there to hand you a stuffed toy. It's a novelty item, nothing more. And the idea came about because I don't have a standard name and every place I go that has a keychain or pocket knife or novelty vanity license plate with common names on them NEVER, not ever once, has had my name, and unless you're one of the people like me with uncommon names you have no idea how disappointing that is. But this idea could solve that easily enough without the pre-planning and waiting. Just minimal effort and whatever it is you have your customer interactive CNC box setup for spits out your novelty item designed by you, average consumer. And if it's completely automated without the need for me whatsoever, then great! But I'd prefer to start out with a less expensive design before going straight for the gold, just to see if the design generates interest when I have it setup.
I'm sure I could find somebody to write a program to do exactly this, but I figured since Vectric already does CNC project design to the nth degree they'd be the best place to start. Whether it's a gadget or a complete program rewrite, I don't know. I'm not a programmer or I'd have taken care of this myself. So I figured I'd ask here.
