Dubble stack mag rack.

This is a handgun mag rack that slides over the gun safe shelf lip to hold your mags under the shelf so as not to take up valuable shelf space. I've seen something like this on here but it didn't fit my double stack mags so I made this one. I am new at 3D design so let me know if it needs improvement. I notice is a little tight for Glock 9mm mags so I will add a version for them separate from the first because it works great for my SIG and other mags.
