Hi again. Apologetically, this may be an ambiguity of language and perhaps some of us don't understand the intended meaning.
When you said "is anyone interested in purchasing and build?"
* Did you mean "interested in buying and building a 1/24 STL"? Or...
* Did you mean "interest in buying and building a 1/24 or 1/48 product as STL 3D print in FDM/PLA rather than wait for future injection mold product"? .
I believe you surely realize many people on this forum deeply admire your creation and would likely want to buy a kit once ready to start a sales campaign.
So if your question is intended to gauge interest, I would strongly advise you do this similar to how ChristopherM did the VF!AG campaign. Announce a date range of when you will be collecting preorders, decide whether you will ask for up-front deposits and how you will collect the funds (PayPal etc), and reveal the final, total price per unit. Otherwise, people here won't understand if you are "formally" announcing intent to sell product, or just polling for general interest.
I think we also understand that you could run a campaign for STL 3D printing now, and a year or two later have a larger, commercial scale offering based on your intended tooling investment for plastic injection molding.
Again, great creation
