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 profile filament clips around the rims! Personally, I prefer these much more than the holes. but tell me what you think. I did leave the holes for those folks that still want them. 06/26/2025 - V2.5 - I decided to revisit this model and see what i could do to improve it. But then a few hours later i had completely remade it from the ground up! I am leaving v2.2 in the other files for those might still want it. v3.2 is unchanged. v2.5 Improvements: Thicker hex lattice better angled filament holes better align
