Corner fitting replacement part for light fixture

I had the missfortune of having a plastic fitting that holds the glass in place break on one of my outdoor light fixtures. I was unable to find any replacement parts so I designed one to be as close to the original part as possible. PLA should suffice as the part is not really subjected to the environment or any meaningful stress. It is covered by a metal housing on this light fixture. An environment appropriate filament would be ASA. Simply swap the filament used in the print profile. I set the infill to 100% since it is a very small part and most printers will probably purge more filament than is used to print it anyhow (< 1 gram). The light fixture in the picture is a Philips Alpenglow - Wall anthracite 60W part of Philips MyGarden series.
