Using promo code "8USDEAL" drops this 10-roll, 10-kilogram bundle of mixed PLA and PETG filament to $58, down from $193. Kingroon's individual spools typically run $10 to $18 per kilogram, so this set works out to well under half that per-kilogram cost even before the coupon. Buying in this quantity suits makers who print often enough to burn through multiple colors and materials rather than someone after a single spool. The coupon ends on September 7.
