Quick release clamp

Printed with easy ABS. I also added an editable file to make it easier to modify.

I used 1 x M6 furniture connector bolt (picture added). I hope it will be useful for you.

For those who want to use only the screw and nut (without furniture bolt), I also uploaded the modified arm and the nut holder for it.

For more details and the accuracy of the print, I use step files - also added.
