Master lock sleeve / protector / identifier

I needed to easily identify my lock in a series of identical locks. The stl file does not have the lettering on it, you can simply add whatever you'd like in your slicer app. I'd recommend PETG or ASA filament, especially for outdoor use. I used .2 mm layers and 3 perimeters which result in no infill. I also think TPU or flex material would be great! Please post a make or any questions! Thanks!
