Painting shield for electrical sockets etc.

This is a simple but effective, hand held shield, to allow rapid and neat painting around standard home electrical sockets, light switches etc. I designed this to cover UK sockets, but it will work with any square edged sockets or fixtures. It's intended to simply be firmly held against a wall fixture by hand, and then quickly painted around, leaving a neat, straight edge, not requiring any masking tape or additional work. I suspect it could also be used in conjunction with a paint roller. There's a large handle, allowing precise positioning and holding. My pictures show it balanced against a switch, as I didn't have a third hand for the photo!

I printed this with PETG and Bambu standard draft profile with 0.24mm layer height - it doesn't need any greater precision than that. No supports are required. I think it would work just as well in PLA, but PETG will be more robust in use and in storage, as the extra flexibility helps.
