I had sorted all the plastic of the vacuum cleaner enclosures by type earlier and visited precious plastic in Malmö today again. We had planned to shred the ABS part of the housings, so we could try to extrude 3D-printer filament from it. Unfortunately the housings were a bit to tough for the DIY-shredder, so we just processed some of the thinnest parts and aborted the xperiment.
