Hello there!
Here's my take on Speed Plate for ASG Glock 17 mag.
As you may know already, original Speed Plates made by Magpul aren't well suited for ASG. Tried to create something with similar functionalities and simple locking mechanism.
It seems to be working just fine with 3 different magazines i have, each made by different manufacturer.
I recommend printing it on left or right side, so the layers will align against the pull force.
