Generating VoxelShapes from model

I would like to know if there is a faster method of generating VoxelShapes in different directions in a less boring way, currently I go to the blockbench, rotate my block to a certain direction, and export the model's VoxelShape in that direction. I have to do this for all six directions (north, east, south, west, up, down) every time I create a new rotating block.

Code:

    private static final VoxelShape NORTH = Shapes.box(0.25, 0.25, 0, 0.75, 0.75, 0.25);
    private static final VoxelShape EAST = Shapes.box(0.75, 0.25, 0.25, 1, 0.75, 0.75);
    private static final VoxelShape SOUTH = Shapes.box(0.25, 0.25, 0.75, 0.75, 0.75, 1);
    private static final VoxelShape WEST = Shapes.box(0, 0.25, 0.25, 0.25, 0.75, 0.75);
    private static final VoxelShape UP = Shapes.box(0.25, 0.75, 0.25, 0.75, 1, 0.75);
    private static final VoxelShape DOWN = Shapes.box(0.25, 0, 0.25, 0.75, 0.25, 0.75);
    @Override
    public @NotNull VoxelShape getShape(BlockState state, BlockGetter p_60556_, BlockPos p_60557_, CollisionContext p_60558_) {
        switch (state.getValue(FACING)) {
            case DOWN -> {
                return DOWN;
            }
            case UP -> {
                return UP;
            }
            case SOUTH -> {
                return SOUTH;
            }
            case WEST -> {
                return WEST;
            }
            case EAST -> {
                return EAST;
            }
            default -> {
                return NORTH;
            }
        }
    }

File generated by Blockbench (using extension) in north direction:

public VoxelShape makeShape(){
	VoxelShape shape = VoxelShapes.empty();
	shape = VoxelShapes.join(shape, VoxelShapes.box(0.25, 0.25, 0, 0.75, 0.75, 0.25), IBooleanFunction.OR);
    	//                                              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ the values used in the static field "NORTH"
	return shape;
}

Remembering that the model from all directions is the same, but rotated.
