This is a version of Captain Slug's VF1 muzzle brake made to be used with dart zone pro blasters. It's a quick and easy way to get extra accuracy from the Nexus, Conquest, Stryker, Dictator, or Tomcat. Be warned though, depending on manufacturing tolerances, the barrel for the nexus and other blasters can be slightly misaligned from the lug, which will actually decrease accuracy. Make sure to test the print before trying to run it in a game.
I printed it on my old resin printer (Anycubic Photon) for the least layer line drag possible, but this should work just fine on an FDM printer at a low enough layer height. No supports are needed and feel free to print at any infill.
In my experience, this increases accuracy the most with full-length darts, which are significantly knocked off course by the air pressure escaping behind them. The accuracy increase for half darts is somewhat negligible.
