Magnetic Cover for ino audio piP speakers

Some mates asked me to make a simple speaker cover ring for their speakers. Since the speakers have 4 screws on the front in a square pattern, this ring has 4 slots for some magnets to fit it on.

Once they glue the cloth on properly I'll upload a picture of it.

Prints without supports, I've done it with both a 0.4mm and a 0.6mm nozzle at 0.15mm layer height.
