IKEA Lack Rotating Latch Plexilock 3mm Drehverschluss

This is a latch to close an IKEA Lack enclosure, it works by rotating the top part and is kept in place by a ball and grove.
I used 4.5x35mm woodscrews and a washer to put it in place. Double sided tape prevents the lower part from rotating freely while open. The top part of the IKEA Lack has a little overhang compared to the legs, I used a 30mm endmill to make the top flush with the leg in order to get the Plexiglas flush with the leg.
