I designed a cover for the ventilation slots on the back of the middle section/cabinet of the Enders UNIQ® 4 IK KITCHEN CRUSTER® SHADOW, as spiders keep getting in there. It should also fit other Enders models.

I sealed the upper opening with a frame and steel fly screen, ensuring continued ventilation in that area as well.

I printed the cover in PETG; it simply snaps into place—done! I made it slightly tighter so it wouldn’t wobble back and forth, so when snapping it on, press firmly with your thumb until you hear a click ;)

Safety note: Since the gas cylinder is located there and the cover might restrict ventilation, use at your own risk!
