This is an magLula-inspired 3D printable AR15 magazine speed loader. Initial versions of this model use a milspec AR15 magazine catch, though a 100% 3d printable version with an integrated plastic catch is also included here. This loader allows for fast loading (and unloading) of AR15 magazines. Using between 50-70 grams of filament (depending on which version you print), this model can be printed for around $3 of PLA+ filament (a 10X savings over purchasing an OEM loader. I encourage you to support magLula by purchasing their magazine loaders if you enjoy their style of products, but the intent behind this print is to be able to cheaply print a bunch, and throw them into range bags/ammo cans/etc in order to save ones thumbs/quickly unload mags without expending excess ammo.
