About this 3D model

UPDATE: I've uploaded the STEP file now for those who wants to adjust the height ect. Infected by Gridfinity Virus i found the grid for Makita MakPacs and thought, great solution to store my screws and other tiny stuff together with other MakPacs of my tools. The grid for the Makpac is great, however there are two corners left and right which are useless. Thats how those Corner Bins got born :-)
