Yes, I see the irony—you’re 3D printing a core meant to replace a recyclable cardboard one. But hear me out! 

Maybe you don’t have (enough) used cores for an amazing model, or you want to test your contest entry before the real deal. This printable Bambu spool core lets you prototype, experiment, and build single- or multi-core models without waiting to accumulate spools. 

So, embrace the paradox, fire up your printer, and get modeling!

Vase mode print profile available for speed and efficiency, only 24 grams and 30 minutes!

For a sturdier result use the 10% infill print profile.
