We're literally up to our eyeballs in empty Prusament spools here and I just can't bring myself to toss them in a landfill. Unfortunately recycling them doesn't appear to be an option here so we're looking for creative people out there willing to put them to good use. Here's a TON of different amazing ideas of what you can do with them thanks to the Prusaprinters Design Contest:

This is for the flanges (sides) only. You can always 3D print another center core if needed. I'm recycling the cardboard ones to save on storage space and shipping costs.
