Minimal Vent Handle for Prusa Core One

I created this minimalistic "handle" for opening and closing the vent. The installation is easy: Remove the middle screw and nut. Place the nut in the handle and flip the screw upside down. I myself keep the nylon part on top to safe the acrylic but I think it's not necessary. 

With good printer settings it's done and good to go, because the nut should sit perfectly in the handle. But if needed, you can glue the nut into the part.
