The Nema17 stepper heatsink gold is a 42×42×11mm gold anodised aluminium heat sink that fits the face of any standard Nema17 stepper motor, combining effective passive cooling with a distinctive gold finish. This Nema17 stepper heatsink gold reduces heat build-up in Nema17 motors during sustained 3D printing and CNC operation, protecting motor bearings and maintaining consistent holding torque. The gold anodised surface provides corrosion resistance and radiates heat efficiently. In addition, the 42×42 mm footprint is a direct match for the Nema17 motor face — no drilling or modification needed. Key Features of the Nema17 Stepper Heatsink Gold Dimensions: 42 mm × 42 mm × 11 mm — direct fit for standard Nema17 motor face Gold anodised aluminium — corrosion-resistant with improved heat radiation Precision-machined fins for efficient passive thermal dissipation Compatible with all Nema17 motors in 3D printers, CNC, and automation projects Distinctive gold finish for custom and visible build aesthetics Use Cases 3D printer builds where motor cooling and visual appearance both matter CNC and laser engraver Nema17 motors running extended high-current jobs Custom CoreXY and Voron builds where gold accents complement the frame colour Reducing thermal stall risk and extending stepper motor service life Works Well With Nema17 Bipolar Stepper Motor 1.8° — the Nema17 stepper motor this heatsink mounts onto Nema17 Stepper Heatsink — Black Anodised — the same heatsink in black anodised if a darker finish is preferred Project Ideas & Tutorials Motor Heat Sink: When and How to Add Cooling — Zbotic — explains when heatsinks are needed and how to attach them to motor drivers and ICs DRV8825 Stepper Motor Driver Tutorial — Maker Guides — covers the full stepper drive chain including current setting and motor thermal management Package Contents 1 × 42×42×11mm gold anodised aluminium Nema17 heatsink
