I think at this point we would say Attribution-ShareAlike
We like this license because we think its fair to attribute other peoples work when you rework or reproduce somthing, and share alike because taking somthing which is opensource and closing it, is not quite fair in our opinion.
In terms of reproducing them commercial etc it would be similar to other companies in the opensource world, our machine is opensource but our branding and identity is not Although we would also like to add i am not sure you could reproduce them at the same quality for a lower price. Maybe if you manufactured the whole thing in china in the 1000s
We were/still are considering the oshwa Opensource hardware license that luzbot and smoothie board use, but it looks like they have quite the legal framework and terms and conditions with fines etc so we want to make sure its the right fit before applying it.
