Stackable Screw Tray Box system

Hey there,I was looking for a help to sort my small screws and parts when dissassembling devices or knifes.There are already some available but they did not fit my needs.So I designed my own interpretation of a system to organize all the small screws and other medium sized parts.Screw_Tray: This is the basic version of the screw tray.Screw_Tray_Magnetic: This version has a higher bottom and it is able to insert 6x1 mm Magnetz.Screw_Tray_Medium: This is a place where you can store slightly bigger parts. It is also stackable with normal screw trays.Screw_Tray_XXL: This is similar to the normal screw tray but with more storage places. (Not stackable)Screw_Tray_Lid: If you have to transport or store the screw trays you can put lids on the top units.You can simply use a rubber band or something similar to fasten the stacked parts.It is also a good idea to mark the different chambers with numbers to get the system even more organized. I printed the parts with a 0,6 mm Nozzle and 0,2 - 0,3 mm
