4x5 half-grid lid for modular Gridfinity box

This is a modified lid for Gridfinity Rugged Box as listed in the remix info. I like to use half-step bins a lot of the time, and this allows me to use the normal body and this lid to store them, as seen in the pictures of my M4 screw storage. If you want sizes other than 4x5 let me know and I'll be happy to add any other sizes offered by the original model. This remix was performed in Blender and seems to work well for me so far. I took the interior of the lid, deleted all the squares except one, shrunk that one down to half pitch, and arrayed it across the rest of the lid for an even grid of smaller squares that allow half-length bins in the box when you want to close it. This isn't feasible with the original and this works fine even if you don't use such bins, but might in the future. Only the inside was modified, as the exterior works better for even half-grid when you simply use regular baseplates instead of trying to make everything half-pitch.
