Blank Key Cover - Type 68

I wanted a cover for a key that I could also insert a label on so I don't forget what the key goes to. I couldn't find one, so I made this blank. I just emboss or remove material for the label I want ("Shed," etc.) using Tinkercad, and within ten minutes I stick it on the key without having to glue or anything like that.

I am sure some tweaking would help, I had to squeeze it on with plyers the last 0.5mm to get it just where I wanted it.
