3D-printing produces a lot of plastic waste due to test/calibration prints, failed/defective prints, and filament color switches. To combat this, we're now offering one-of-a-kind key charms with recycled filament!Each charm is made out of scrap filament which is pressed down into colorful abstract sheets of plastic, which we then cut into desired shapes. This listing includes a small assortment of charms we've created out of plastic sheets we already produced, but as more pressed sheets become available, we are able to offer custom cut shapes, which will not be limited to key charms. Due to the nature of our collection method, we cannot promise specific color combinations for these pressed plastic sheets, but will be able to post photos of them as they are created so you can see the general appearance of the material used. Despite the unpredictability of this processing method, we are always open to requests, so please feel free to send us a message with any preferences or questions!
