An alternative version of the spinner base exists with a negative offset, making the bottom edge 0.3125 inches below the prop adapter. The second variant features a normal offset of approximately 0.050 inches. Both designs accommodate a 9-inch propeller with a diameter of 6-7 inches and three blades. The spinner cap remains consistent between the two base types, attaching to the base using M3x12-14mm socket head cap screws. This design aims for lightweight performance but has not yet been physically printed for testing.
