I got this ide when i was printing a flower pot that failed, and i liked the form of it and have used that as a tray.

But then i wanted the possibility to stack them, and organize the trays. And with that i got the idea to organize them with the help of magnets to chain them together.

I made them stackable by reducing the size of the bottom to create a notch. Was thinking of expanding the top of the tray instead but then it would create problems if you mix magnet trays and non magnet trays, by have a notch at the bottom, all the versions can be stacked.

Size of the tray: 100mmX100mmx32mm (wide X long X tall), 30mm inside (without the notch) Size of Magnet recess: 10mmX2mm

Print time V2PolygonStackBoxBasic: I use a 0,8mm nozzle, 20% infill and no supports and it took 1h 46m
