This is a showcase of the transformation of rotational motion to linear, in the form of a gag gift, the cover might not want to grab onto the bottom plate, so if that's the case just use tape, and yes, if you spin the handle, you will be officially designated as a "booger eater" sorry not sorry.
This was printed on a Ender 3, so if you have somthing better the print will most likely come out cleaner. Feel free to take this idea to the moon, add your own custom messge or what ever, if you have any questions just put it in the comments and i will get back to you, maybe.
The author marked this model as their own original creation.
