Ender 3 Z screw protection

thingiverse

I have a plastic dust cover that I throw over my Ender 3 when it's not in use. I'm usually careful when putting it on and taking it off that I don't snag the Z screw and accidently bend it. Since my family is using the printer more these days, I designed this thing to just protect the Z screw but leave it free to move (the Z screw is not 100% true/straight... holding it captive with a bearing or something will result in artifacts in your prints).
