Attempted, untested, thrown together, unrefined external rayven magwell.
In 2 parts so you can still open your shell once you epoxy or plastic weld this bad boi onto your blaster.
Give me feedback on this if you can, I want to know how long it stays on, or if it needs tweaking, if it can even fit mags through properly etc. Let me know.
Once done printing snap off the support boxes below the thin wall, as shown in the grey picture.
Make sure you allow for printing thin walls!
