@MarcinSuchoc_1507055 I've uploaded v7 of the back covers and frames, which corrects this. v7 frame is necessary as I've also reworked much of the frames and back covers, so the ribbed sides will not match between v6/v7.

@KT9Q_308184 Same thing happened for me.
T-Beam_v6a_back has a weak spot that can be damaged if you're not careful as the wall is only about .55MM thick.
This is NOT a slicing issue as you can't slice the model to be thicker, as you can see the wall is only .55 when you bisect it in freecad. (edited)
