Lens boards standard measures?<\/h2>\n\n\n\n

I just wanted to have a comprehensive list of all boards, etc., to actually use all cameras in my foolish collection. I just hope I can help other people sharing the same illness.
I try to list ALL GOOD TESTED free sources for those who have a 3dprinter. I developed my ones, and sometimes I released for free. I’ll soon consider to sell them as a final product. Designing and making them costs a lot of time and effort, and sometimes requires experience and skills, and I have less trouble making them than trying to help people and keep my “digital reputation” on Thingiverse or other places.<\/p>\n\n\n\n
