AR-15 Magpul One and Six Mag versions. It also works with Lancer/similar mags without a base plate; however, it is a friction hold and not as effective.
Allows forward placement of magazine with positive retention.
The prints are a better way to store firearm magazines on a multiboard. They allow easy installation and magazine retention. They will allow forward removal and placement of magazines.
Print the six version upside down with .20 layer height, 3 walls, 15+% infill, and automatic tree supports. One mag version print in normal orientation.
To install, insert the top portion of the snap into the multiboard and rotate down until flush. It holds a heavy load so it will take some pressure to lock it in. It may be a problem if the multiboard is spaced off of the wall. I may reduce the mounting snaps, it is probably over-engineered!
