Juno Blaster - Handle Insert with No Sling Point

I absolutely love the Juno blaster from Out of Darts, but I really didn't want the sling point in the handle. Since it was a separate part, I figured I'd modify the original to remove the sling point and keep everything else. 

It fits great. The downside, however, is that since there isn't anything extending out of the handle, it's a bit of a chore to remove it. But, it can be swapped out with the original part when desired. 

I would suggest printing with 3 perimeters all around and 15% infill.

I uploaded the original STL to TinkerCAD and simply removed the portion of the model that included the sling point. Nothing really innovative here, just a minor modification.
