Kids accidentally touch our printer, stop 80 hour prints half way through and make us cry. Thus the z18 Cover. It fits in the USB section, so if you use that this isn't for you. The part of the print that goes into the USB section is designed to be loose. Please add some foam to span the space. We decided to go this route because it makes a nice fit and makes it so it sorta squishes in there a bit so it stays without scaring the printer.
This thing was made with Tinkercad.
