Dart Zone Max Solo Mega Adaptor

WIP model for a nerf Mega Dart adaptor for the Dart Zone Max Solo

Needs the following work:

Refined internal base geometry. Currently needs some slight filing for a smooth fit.
Thicker internal base
Thicker outer walls
Maybe a slightly looser barrel for better performance
Fit over original  barrel is extremely tight for my setup. May need refinement
Need more flair!!!
