Now in the beginning I use the standard PLA filament. On this bracket there will not be any hard force acting, I think it will be strong enough. I have added som extra structure to the bracket to have it flex less.
6 days after version 2 is now version 3 in the printer and prints out. It's all the small details that take so much time and the lack of experience of CAD drawing. Very often it complain of broken lines and it's hard to find when the structure is complex.
Look at page 4 to 6 for the last details:

When this bracket is finished I start drawing tube rings to the guider camera and lens.
