This is really cool.

I would love to see more details about how the engines are 3d printed, and the plans for the designs. Will these engine designs be open sourced?

Also, the rewards are a little difficult to parse. A list format would probably be easier to read, rather than one sentence with each reward concatenated to the rest with 'and'. I think having the 'all previous rewards plus ...' is a better format as well, but that is more personal preference.

[EDIT]

Further, there is no break down of how the money will be used. It seems like 'give us money and we'll do cool things with it' but without any clarification of how much money is really needed to do those cool things.

[EDIT2]

There is a pretty amazing blog over at Rocket Moonlighting [0] that contains a lot of details around 3d printed rocket engines. Well worth a look.

I am the creator of the project. It is unlikely that plans and designs will ever become open sourced. Considering experience of DefDist and their issues with State Dept because of open plans of "Liberator" gun, we are being careful not to expose designs to outside of United States.
