My print room is furnished almost exclusively with IKEA Kallax bookcases so I tweaked Zach Friedman’s excellent Gridfinity grid to fit into the Kallax drawer inserts.
It prints, as the original grid, fine at 0.2mm. My only problem was that I only have Ender 3’s of varying types and none of them is the Max, so I had to split the grid into quadrants.
