Replacement E3D 2 Wire Molex Connector Set

These connectors are used on most all E3D Hotend components, such as the extruder fan plug, the thermistor cartridge (or Pt100 / PT1000), Part Cooling Fans, and even on Premium Grade (Green Wired With Disconnect 24V) Heater Cartridge.

These Molex Connectors are officially known as Molex Micro-Fit 3.0™ Connectors.  We have finally received permission to distribute the officially licensed connectors (Authorized Distributor - which is part of the reason these are so impossible to ever replace as this validation must be granted to even sell this brand's products!) that no clone can rival the quality and perfect  size and ease of use for 3D printer hotend or any part you wish to have a quick detach for! 

However, we will also provide kits that allow any 3D printer builder to use these excellent detachable 2 core wires for any and all of your hotend components to easily detach from your hotend wiring loom! 

These connectors once gone bad, or accidentally come detached means there is NO WAY to ever fix your various hotend components that use these very special connectors. We use them in our builds so frequently and have stripped, torn, or accidentally cut an E3D component using these wire connectors and found that they are VIRTUALLY IMPOSSIBLE to source!    LOOK NO FURTHER, G3 Productions has you covered!

  • Where we will include not only the male and female Molex connector body and pins but also these paired with various wire lengths (e.g. 1Meter, 2Meter 2 core wire length) attached to one side to run to your printer's control board and allow you the ability to connect the other connector over any existing 2 wire component (Fans, Thermistors, Heater Cartridges, etc.) For easy detachment!

Note we also supply Molex Micro fit 8 pin Connectors for most hotend quick disconnecting!
Especially useful for tool changer tool wiring connectors or to overhaul any printer's basic hotend with a single connection wire! Imagine your Ender-3, CR-10, or Ender-5 having a nice braided sleeve of all wires to the hotend and being able to quickly disconnect the wire loom from ONE connection! Perfect for people swapping out hotend types or to maintenance hotends easily without having the wired connection to the printer holding you back from proper maintenance or cleaning! Also for those who would like to do laser etching or other swappable tool ends on their printers this is a clean way to make a single connection for all your standard hotend components!

A full range of sizes is available upon request as an official Molex brand Distributor! We have any plug option you require for a nice and tidy wiring job for your machine!

Clean up that ugly look of the 4 stepper motor wires in a fan or all lose! These also come with colored PET sleeve options to match your printer's look and theme (Black 

For those who have direct-drive printers and have counted your total number of wires to your hot end; We do also offer 12 wire connectors
(For direct-drive extruder wires 4 more needed for the stepper motor) and even larger ones with a double row of 16 or combining the 12 with a 4 pin separate connector to wire up bed leveling sensors such as a capacitive, inductive, IR, or just a basic limit switch!  

And for Bowden Drives [Hotend not needing the extra 4 motor wires]
8 Pin Connectors are perfect for fast hotend disconnection for maintenance!

Regarding the 8 pin connectors:
