A few unfortunate updates:
International shipping: three strikes, and we're out. I can no longer offer any form of international shipping, as parcel shippers reacting to current world events have made any level of shipping cost commitments impossible.
I have also made the decision to begin winding down kit production, as the current printer I have is reaching end of life and cannot reliably print production runs. The kit costs needed to justify new printer capacity are not feasible based on sales volumes of current kits at current prices, even if just to break even. CAD models are currently not for sale, as releasing those into the creation space would just undercut my ability to sell the inventory I have to recoup costs.
I really appreciate those who have supported me in this great experiment, and will re-evaluate conditions in the future.
