Airsoft CYMA AK Dust Cover Button

I needed a new button/latch for my CYMA 0.50 and couldn't find a model online, so decided to model a quick and dirty one. I measured the rails and the hole that it would need to slot into, added two holes on the side for a grub screw. Print in PLA+ or PETG, it's a very low stress part and mostly there to keep the cover on.
