[Discuss] Going open source. Need assistance

[Pablo Kulbaba]

Hi. I'm on the process of open sourcing a piece of hardware. I've 
decided to take the step and give OS a try with some of my own work.
Already have the 3D model.
What would be the practical steps to properly do this?
Where do i register it?
Any repository to recomend? GitHub?
Stamping the license on the drawings? What about doing it on the 3D?

Thanks in advance.
