Tokyo Marui MWS GBBR Drum Magazine Latch

So there's a drum mag for Tokyo Marui MWS GBBR. I'm not sure the exact name for it, so for reference:

These latches are essential for reloading the mag and for maintenance. And when some of them breaks...

This shape is kinda messy so orient it however you will and add supports.
High wall count may also ensure its strength.
