Quick Release Spool Adapter for Universal Motorcycle Saddlebag Supports

I made this because I didn't want to buy OEM spools from Indian Motorcycles for $180. ( https://www.indianmotorcycle.com/en-us/shop/accessories/storage/bags-luggage/2884925/ ) Used on this generic saddlebag support system from Street & Steel: ( https://www.revzilla.com/motorcycle/street-steel-universal-saddlebag-supports?sku_id=1136599 ) Used to mount this sissy bar, although it should fit most mounts with <3mm thickness: ( https://www.etsy.com/listing/1493418654/indian-touring-and-chief-everything?ls=r&ref=items-pagination-10&frs=1&content_source=c0aa20ac146fe665d490e7ef6adbade1%253ALT5fe5b2ad6f52a1659eaa94c2aaa0d3e1685ee64c&logging_key=c0aa20ac146fe665d490e7ef6adbade1%3ALT5fe5b2ad6f52a1659eaa94c2aaa0d3e1685ee64c&variation1=3592550644&variation0=3609123413 )
