Gridfinity Removable Bin Lid v2 - Stackable(ish)

I initial thought that design is wrong and that it won't fit, but after few attempts I finally got it - you have to put it angled inside, place it in right place and pull up till click - just like author described in the file details. It was still very fiddly and there is visible bulge (as in photo). I don't know if that side deformation could be removed by better fit or if required by design.
I love how it looks when it works and that this is perfectly stackable solution!

I have the same problem as Mat.
Wrong design.

I printed it upright as the geometry looked like it was designed to be printed that way.

It could be made to fit my 2x1 gridfinity box but really it bent the sides of the box and the tolerances just didn’t seem to work. Also I wasn’t able to stack anything on top. Maybe my print settings? (0.6 nozzle and 0.4 layer height) but I print everything like that these days and don’t usually have problems with tolerances…
