QR Code Cover
thingiverse
A simple cover for the QR code at the end of the gantry can be easily created with just a plain cap and one with a spiral design that are included in the download. These covers are set to 44mm, but you may want to consider printing them at 43mm to ensure a snug fit. Testing has shown that 44mm is a bit loose, but still fits well enough.
