Here's my Sudomod Logo Ender 3 X-axis QR code cover. I designed this to hide the annoying sticker and give my printer a nicer look.
Works great! Prints fast. Clips right on!
I have a BitBuilt version as well.
I also modified this to be a Minty TinkerBox as well. For all those left over Altoids from your V3 builds. ;)

Please post your prints, and don't forget to Like the thing!
Print face-down for ease. No supports needed.
I used a calipers to measure the size of the housing on the X-axis, and then after watching Adafruit's Parametric Snap Lid tutorial, I was able to add some ridges inside at a 45 degree angle to keep it on your printer snug.
