After a long break due to several other projects, I returned.
Unfortunately, the next printout will go to the trash. It is a pity, Sossenfetischist, that you did not write about the enlargement of the panel. I added my 3 mm and it turned out too big now.
Is it possible to correct the selected errors? The frame and the hole are missing from the inside. From the outside it would be useful to tighten the notch.
