Show Woocommerce Product “attributes/extra information tab” in widget [closed]

Checkout the content-single-product.php WooCommerce template for an idea of what functions are hooked where. It is very well commented.
The following should remove the additional info from the tabs:

add_filter( 'woocommerce_product_tabs', 'wpa_116999_remove_info' );
function wpa_116999_remove_info( $tabs ){
  unset($tabs['additional_information']); 
  return $tabs;
}

And then wherever you’d like to add the Additional Info you’ll just need to called the woocommerce_product_additional_information_tab() function. I wouldn’t bother registering a widget. Depending on your theme you can either add it to a relavent hook in your functions.php, or create a child theme and paste it directly into sidebar-shop.php or sidebar.php. It is hard to be precise on this point because every theme is so different, but that’s the general idea.

In your functions.php, editing the fictional sometheme_before_sidebar hook to an appropriate hook for your theme:

if(function_exists('woocommerce_product_additional_information_tab'))
     add_action('sometheme_before_sidebar', 'woocommerce_product_additional_information_tab');

or directly in the child theme’s sidebar.php file:

if(function_exists('woocommerce_product_additional_information_tab'))
    woocommerce_product_additional_information_tab();
