Filament Exchange (Hosted by Polar Filament)

Leave a spool, take a spool. Exchange your unwanted filament with other people at MRRF. This is an opportunity to try new brands and materials while also finding a home for those old spools that you don’t think you’ll ever use again.
Stop by the Polar Filament booth if you’d like to participate.
At the last event, over 600 spools were exchanged!
