Also, kitsch, I have access to a 3d printer, so if you want me to print out the current model with the plastic we've got just to see how it works before you commit to getting it made, I can do that with pretty much zero issues.
hmmm, possibly. the mould I can have revised as long as its not 'hardened', after this I can't make changes. so, its not quite so one-shot...
but, this is a really nice offer regardless, you could even make yourself a case if this happens!
can you do this with *.stp files, or whats the format you'd need?
