Kingroon Silk PLA Tri Color Filament, Multicolor 3D Printer Filament, Dimensional Accuracy ±, 1kg Spool (2.2lbs), for Most FDM 3D Printers, Red Green Blue

Budget hardware maker that sells filament alongside its printers. Prices are low; the catalog sticks to standard PLA, PETG, and a few specialty variants. Not the place to shop for engineering materials.
