Cardboard Spool holder / ring for Bambu Lab AMS

The AMS system from Bambu labs doesn't play well with the eco friendly cardboard spools some filaments are now coming with. This is a work around for that. This fits the 200 mm cardboard spools used. I typically use Polymaker, this fits that snugly and is very reusable. These items ship in pairs since you need two per spool. First set is 10$, but just 3 for each additional set that you want. Bulk orders are available with planning and negotiated price, shipping is included in fixed prices.
