This is a customizable Gridfinity base. You can choose a grid size of 1x1 all the way up to 8x8.  In the parameters you can choose 1 for the Regular profile, or 2 for a Light profile.  On a 5x5 grid, the Regular takes 35g of filament.  The Light takes 22.5g.  Thats a 36% less filament.  Print times are about the same. 

You can change the size of the grid spacing if you like. However, the standard size is 42x42 grid spacing.  If you change this, standard bins will no longer fit, and you'll need custom sizes. however, sometimes half size grids (21x21) are nice for filling space in drawers. You can find bins with half grid sizes on Makerworld and other sites.
