Reshell your dart zone bcar as an internal BCAR for the Venom Pro.
Prints without supports
Requires a little shell cutting to make sure the lower rollers don't collide against the trigger guard assembly.
Only fits with upper rollers at a diagonal and lower column facing down.
Scale the cap vertically as necessary to adjust the fit into shell's muzzle.
Becomes much pickier with darts. Try experimenting with removing stages of rollers.
