This is a Fully modular Handgun storage system. I know there are many Handgun storage systems out there but I developed my own spin on it. Everything I found required you to source and purchase various nuts, bolts, externally and or internally threaded rods etc. So I designed a fully modular system requiring no hardware other then your 3d printer and filament. Just slice, print, assemble and store. easy as that. The storage capacity of this design is only limited by the size of the space your storing you handguns in. Enjoy
