E3D J Head 40mm x2 Cooler

Tired of seeing all of the Part/Cold end coolers out there with a 40mm and a 30mm?! Well here ya go! BOTH are 40mm fans. No more adapters needed! Both items mount together. No nuts required. Just thread the M3 bolt right into plastic!

*I do not take credit for this part as my engineer bud is the one who designed it.

Thank you and enjoy! Embossed with the Prometheus-3D Trident
