This is a remix of the SBox for MK2/3/4 - Double cantilever box to fit the Ender 3 build plate (235x235) as the original does not fit (247x247).
Basically I shaved off 2-2mm from the bottom part next to the handle as well as from the handle (so the handle is slightly thinner now).
Also I had to shave 2 mm from the hangers for the top. So I recommend printing those parts with 100% infill or full walls so they are strong enough.
I also uploaded the parametric design if anyone would want to make changes or fine tuning.
