The Calvin's 3x3x5 Fisher Rocket V1 is a 3x3x5 shape mod that is the combination of the 3x3x5 Fisher Barrel Cube and 3x3x5 Fisher Cuboid. The top 3 layers are from the Fisher Barrel Cube, and the bottom 2 layers are from the Fisher Cuboid. This pattern makes solving the Fisher Rocket V1 a unique challenge compared to the original 3x3x5 fisher cuboid.
