AMS stacking bracket NOT fully validated

I'm planning on buying a second AMS just to use different materials (not for the color). I spent a week designing this 2-tier stack, completing many fit tests, but chickened out before the final product could be printed. I knew it would be big, but I didn't expect it would require 3kg of filament and the printing time would probably be more than a week (I don't run a print farm and don't have a printer that works non-stop). I'll put it here anyway, maybe someone with some time is willing to make it a reality. If you are successful, please be sure to share a photo of your finished product with me. Or someone could make it less heavy (I apologize for my aesthetic). The part of the model that matches the AMS has been verified. If your AMS is like mine, there should be no problem with assembly. I'm used to designing to tighter tolerances, if you don't like it try the critical part first. I hope someone can use this part to make something else. I only uploaded the left half of the model fil
