Nerf Drain Blaster Shell

What's the only thing better than a big ol' Nerf missile launcher? TWO big ol' Nerf missile launchers!

My first go-to was the Titan, but those are few and far between these days. The Drain Blaster, on the other hand, is more readily available. It works okay, but the ergonomics are trash; I measured the handle at something like 80° from horizontal! That might work for shooting toilets, but not darts. I had to have a more comfortable and useful way to shoot the thing, and here we are.
