Looking into different licensing options I found that they seem to be done mostly software distribution in mind. Creative commons seemed to me most suitable for my case of work so I chose that.
For example MIT license is mainly a software license (not like Creative Commons that is targeted to creative work). When using MIT licence it gives total freedom for any person to obtaining a copy of the software and to modify, distribute, sell or sublicense the software. The only condition is that the original MIT license text should appear in any derivative work, even if the license changes. Link to MIT licence page.
By chosing Creative Commons Licence I release everything through my web sites under Creative Commons Attribution 4.0 International Public License™. My project was made for Fab Academy 2017 final project. I used Autodesk Fusion 360, Freecad and Autodesk 123D programs for 3D desing. For 2D Design I used Inkskape and GIMP2 software. Electronics was designed with Eagle PCB freeware software. Also I have used multitude of open source and free software to support the process. At this point I have no intention to commercialize my product. Details about Creative Commons Attribution 4.0 International Public License can be found here. There is no intent to commercialize this product. If I would consider commercialization, first I would need to get an agreement with the company building the actual through hole plating machine. My device is an ad-on to a commercial product by a German company Bungard Elektronik.
All my projects are available to free use or even developing in parts that have origin on my design.
There is no intention to make any incomes with this project. It will make ease my and my co-workers work load when possible. It will also make the pcb manufacturing process faster and doing so shorten delay of delivery to the customer.
To commercialize the product I would need to re-do the machine after testing phase on my lab. Then I would need to consider better materials, minimize material usage and maximize durability and maintenability. After re-design I would need to re-test the machine and consider getting all the parts from 3rd party suppliers.
I see the need for this type of machine quite marginal so only on demand selling would be viable.
