I am working on it for a while, and you don't know how much I had to make a simple version so I can sell it.I had to reduce the parts, make thick details, and simple mechanism only.
The personal design, my real project, is much more complicated, but it makes 2 times the printed stuff is just not good enough to match my desire, too rough, off shaped, it would need a much more elaborated process to get a working design, I am thinking about it.
