Z-Axis Sheath Guide

So what it is, is all in the title. But not may not be clear without the context of the situation. So. Not that long ago... In a spare bedroom, that is like really close. Because I happen to be sitting in it... A 3D printer was being used.... To print extra ellipsis... ... But really now. Back when I was unboxing and assembling my Ender 3. The Z-Axis screw rod came in a black (shrinkwrap?) tube for protection. And once I was finished with said assembly, I knew that the screw rod could be a failure point if dust/debris got in the threads. Or more specifically; I have cats. There is shedding. EVERYTHING is covered, or will be covered, in fur. So I slid that tube right back over the screw rod. Ok. But what in the heck does that have to do with the printable object? I'm getting there. It's just a bit of a journey. And to be honest. I'm typing this all out no matter if you read it all or not. So, you can either go through the rest of your life knowing that your momma raised a quitter. Or you can like finish reading all of this. Because... ... ... Any who. I eventually tried out a roll of ProtoPasta Matte Fiber PLA (Great stuff) on one of their cardboard spools. And what do you know. The edge of that cardboard spool would catch on the top of that black tube I use to keep my screw rod free from loose cat fur. Then the spool wouldn't turn. The filament could potentially not feed. I had to actually manually unstick it like three times. W? T? F? While I could have fixed that problem by simply sliding the spool mount 1/2 an inch to the left. NO!!! I have a 3D printer! I can design a 3D printed solution to that problem! Why? Because ENGINEERING!!! So yeah. This object just gets stuck in the top of that plastic tube. Just so a cardboard spool won't possibly get caught up.
