Ikea Moppe Drawer

I've been trying yo use the gridfinity system and since I have a couple of the IKEA Moppe i figure I'll try to use gridfinity in it. Unfortunately the dimensions of the smallest drawer can only fit a 2x3 grid, with plenty of waste space left. I designed this replacement drawer with the grid already integrated, in this way we can fit 3x4 grid, with no wasted space.
