So I did the math (for the small drawer, 84x39cm) and turns out I needed a 17x8 grid, which I divided in 6 4x4 and 2 5x4 sub grids (for A1 mini users, that means 8 4x4 and 2 1x4), bolted together. The grids were generated with the super useful Gridfinity generator from Perplexing Labs (https://gridfinity.perplexinglabs.com). For the large drawer (84x54cm), you can fit a 17x12 grid. So it's 9 4x4 and 3 5x4 sub grids. (For A1 mini users, that means 12 4x4 and 3 1x4 sub grids) Once the grid is assembled and you put it in your soon to be magnificent dr
