XXL two-tier stackable shelf

Hello friends,following my previous shelf model, I came up with the idea of an XXL two-tier stackable shelf, thanks to which you can use the volume of your printer to the maximum ;-) thanks to the maximum dimensions it is very stable and at the same time can be stacked to a great height :-) I hope you will find it useful. As the last one, I am attaching 2 printing profiles, I recommend printing from PETG, at the same time, you can choose between a full or lightweight version, which will save filament at the expense of lower load capacity ;-)
