Cardboard Spool adapter for 193mm spools to work in AMS

bought this spool of filament as i badly needed limegreen (don't ask) - Amazon.com: DO3D Lime Green PLA 3D Printer Filament, Tidy Winding High Diameter Tolerance 1.75mm PLA, Widely Fit for 3D Printer/3D Printing Pen; 1KG 2.2LBS Cardboard Spool 3D Printing Material, PLA Lime Green : Industrial & Scientific

Spool was cardboard, and 193mm in diameter. Does not work in my Bambu AMS…. at first, i thought all it needed was a 193mm sized plastic adapter. So I found this - Cardboard Spool Ring for Bambu Lab AMS (parametric) by Blizzard | Download free STL model | Printables.com and resized it to fit my 193mm spool… but it was too small… and still wouldn't work. So i made another, by adding a thick rim - and i have a 193 to 200mm adapter. It's a quick print… and works great in the AMS now. 

Hope this helps someone!
