I wanted to use the Strong Lack Brackets by @Stigern, but I also wanted to mount Gen2 drawers over the full width of my Lack. The solution was to use two prints of the original design on the rear side and two slimmer “half” versions that do not collide with the drawer modules.
For me, this is a nice balance between sturdiness and functionality.
The author remixed this model.
Reduced the design to be attached only on one side of the Lack leg instead of two.
