I had trouble with the legs of the lack enclosure being able to wobble when smaller screws were used to fix the legs into place.
There was also trouble with the acrylic panes bending due to the spacing between the acrylic fixing points being just 2mm to close to eachother for 440mm square panes.
This model has been designed to account for both of these issues, giving a total of 4 offset fixing points all around the top of the leg, and being 2mm thick to increase the distance between the fixing points ever so slightly.
Simply print 4 of these pieces and affix to the top corner pieces with superglue.
The first iteration didn't have the large fixing hole line up (visible in pictures), this has since been corrected.
The author remixed this model.
