This one was kinda hard to name… but my new Prusa CORE ONE 3D Printer has a little grill on top, that you slide open or closed depending on what kind of material you are printing, to help with temperature control inside the print chamber. But since I’m always using PLA, it’s always supposed to be open. Once I guess I accidentally bumped it and closed it, so I thought I should like to put something in the grill to keep it open.
