22-piece aluminum heatsink kit for stepper drivers

This set supplies twenty-two blue aluminum heatsinks sized 9 by 9 by 12 millimetres for passive cooling of stepper motor driver modules. It targets builders of 3D printers and CNC machines who need to dissipate heat from TMC2130, TMC2100, A4988, DRV8825 or TMC2208 chips without adding active airflow. Each piece weighs roughly .04 ounce and ships new.

Pre-applied thermal adhesive tape simplifies

Every heatsink carries a layer of thermal conductive adhesive tape on its base, so no separate paste or glue is required. The tape bonds directly to the driver IC once the protective liner is removed, cutting assembly time and ensuring consistent contact pressure across all twenty-two units. Stepper motor driver modules themselves are not included in the package.

Compact 9-millimetre footprint fits dense board

At .35 by .35 by .47 inch each, the heatsinks occupy minimal board real estate, allowing placement on tightly spaced driver modules common in 3D printer control boards. The low 12-millimetre height clears most enclosure lids and wiring looms while still providing a measurable thermal path to ambient air. Blue anodised finish resists corrosion and aids visual identification during maintenance.

Questions about this item

Will the adhesive tape on the 9mm x 9mm x 12mm heatsinks need replacing after long use?

The thermal conductive adhesive tape is pre-applied; if it loses grip over time, new thermal tape or paste can be used to re-secure the blue aluminum pieces.

What thermal limit appears first when these 1 gram heatsinks run continuously on stepper drivers?

Passive aluminum mass saturates quickly, so the heatsink temperature itself becomes the limiting factor before the driver throttles.

How much noise, heat or extra power do 22 of these blue aluminum heatsinks add when the printer runs all day?

They add zero noise and zero power draw; they simply spread heat from TMC2130, TMC2100, A4988, DRV8825 or TMC2208 modules into the surrounding air.
