The Airsoft M249 MAG Brand Box Mag Speed Loader Funnel is a free printable 3D model from Cults3D by JollyFancher. We love the MAG brand box mags, they are very reliable, quiet, and hold 2500 rounds, but loading them through the tiny door is awful. You can download the STL file from the original listing below and print it at home.

About this model

We love the MAG brand box mags, they are very reliable, quiet, and hold 2500 rounds, but loading them through the tiny door is awful. I made a quick funnel to help with loading. I tried a couple different designs, but this was the easiest I found. Its not perfect, but its better than before. Also have a smaller version that is about the same size as a 9v battery, so it will fit in the mag itself if you have it wired differently and no longer need the battery in the mag.
