Bambu Reusable Hex Spool

The rims and center ring are straight from Bambu's spool. And interchangeable with it. It is designed for Bambu's refill spools. But I have found that Elegoo spools also fit perfectly on it. Also Overture and Polymaker spools fit but are a bit loose, but they fit perfectly over the center rings of Bambu and Elegoo spools. So, I use them as spacers. Let me know if you try it with any other brands!I recommend PLA because it is a lot stiffer than PETG. 11/19/2025 - V2.6 - I added low profil
