I got back into 3d printing after a terrible time. I love it now but even with all the advances you still have to take apart things.
You think that I'll be able to remember how to put it back together and which screw goes where……Yeah I severely overestimated my memory on this. When you are pulling something apart and putting it back together you don't want to have a lot of bits and bobs left over. If you do you then are waiting for that catastrophic failure/fire. (Fire hasn't happened but you never know)
So I made this simple tray as you pull apart each thing put it in order of the tray when you are ready to put it back together turn it around.
