L Profile for Flyscreen Window Corner

My flyscreens corner parts damaged because of too much exposure to sunlight. Couldn't find anything that suits me so I tried to design a part to fulfill my needs. I didn't test it for melting or anything so maybe 40 percent infill could be overkill or it can melt from direct sunlight I don't know. It's 63x63x14.3 mm. No supports needed but its up to you. Also added a step file if you need it.
