A quick remix of Red Cowl's excellent extended muzzle for the Dart Zone Outlaw foam dart blaster, which incorporates either 3 or 4 vertical cuts to resemble a muzzle brake. Visual inspiration comes from the muzzle brake on the Desert Eagle amongst others, and I think it adds to the futuristic look of this already visually-appealing blaster.

Print with supports with the muzzle end on the build plate, from a bright orange filament for safety.
