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
