Nema 17 Stepper Motor Aluminum Heatsink for 3D Printers(GOLD)
This heatsink is designed for Nema 17 stepper motors in general and specifically in extruders. It does not only act as a cooling heatsink to lower down the temperature of an extruder but also to cool a stepper motor within an active heat chamber. It has a round hole in the middle of it allowing for a teethed extruder gear to pass through allowing you to see it in action. Two mounting holes of size M3 exist on one side to mount the heatsink onto the stepper motor. Sold by the unit.
