Cool.
Some of the parts look right, others don´t. I guess it´ll be impossible to find all the needed ones in the right size, but what you´ve found already is a great effort.
Even the parts that are very similar are still off somewhat. Plus I don't think the high-resolution 3D printing is high enough resolution to make exact parts - also it's expensive!
IMO, though, it will be much closer than the SMT Y. The only way I can get it exact is to make a series of naptha-filled molds, which would also be expensive, or start my own injection-molding model kit company. Speaking of the Naptha - if I could even get that to work, how much would someone even be willing to pay for a kit of it?
