Have you ever thought: where am i going to store my nozzle's?
The answer is right here, I created a box to fit 20 E3D-Nozzle's. It is a very easy print, the tolerances are already done. In the beginning the lit does not slide well but slide it a couple of times and the slide gets smoother.
I hope I can help to answer your question about where to leave your nozzle's.
Thanks, and please follow me for more.
