Very inspiring project. Maybe you would want to consider selling your mould (looks like it is great quality) on the bazar, and that could be a very "quick" way to collaborate, much like sunshade glasses projects that are there in the form of moulds (i cannot afford to partecipate and buy them for now, though). Anyway keep us informated on your progresses and share something about teams that are using them. Which ages are the players using them?? Greetings!
