Gridfinity Refined Lids

Although the originator posited he liked to see everything, nothing in his way to get grabbing, I find that better storage still has all it's properties, but with a lid.  Designed all from 1x1 to 6x6 in every variation.

Probably only thing you could do to save time and a bit of plastic is thin the top by 1mm, as it is 2mm tall in thickness, but I like that it actually serves as a nice work surface when it's not living it's purpose to serve parts.
