Creating custom Bootstrap utilities using SCSS maps is an efficient way to maintain consistent spacing across your project. You can define your custom spacing utilities in your SCSS file and compile them with Bootstrap's source files.

<!-- BEGIN COPY / PASTE -->
        // Step 1: Define your custom spacing scale
        $custom-spacing-scale: (
            '3xs': 0.125rem,
            '2xs': 0.25rem,
            'xs': 0.5rem,
            'sm': 0.75rem,
            'md': 1rem,
            'lg': 1.5rem,
            'xl': 2rem,
            '2xl': 3rem,
            '3xl': 4rem
        );

        // Step 2: Merge with Bootstrap's default spacing scale
        $spacers: map-merge($spacers, $custom-spacing-scale);

        // Step 3: Import Bootstrap's utilities to generate classes
        @import "bootstrap/scss/utilities";
        <!-- END COPY / PASTE -->

Additional Comment:

Define your custom spacing scale using a SCSS map with keys representing the size labels and values for the spacing amounts.
Merge your custom scale with Bootstrap's default `$spacers` map using `map-merge` to ensure both default and custom spacers are available.
Import Bootstrap's utilities to generate the CSS classes for your custom spacers.
Compile your SCSS to CSS to apply the changes to your project.
