Whenever you are making an item which involves many parts do you just throw them into one container. And then have to sort them out before final assembly assuming you can’t build as you go.
This is what I do I have a portioned box and keep all the parts for that assembly in one part but I also label with little tie on tags if there is a hole to attach them to If I can’t attach a label I have a number of these small containers with a bit of masking tape so I can write what is in there. They are also handy for mixing small quantities of paint when needed.
