Bondtech upgrade kit for Wanhao I3 & I3 Plus


Wanhao i3 Kit

Bondtech upgrade kit for Wanhao I3.

This kit provides a high-performance material feeding system with the ability to print faster with improved quality. The adjustable thumbscrew allows you to fine-tune the force acting on the filament.

The housing parts are professionally SLS printed in nylon for maximum strength and precision.

Upgrade Kit Benefits

The quick-release lever lets you load and unload filament with ease for quick filament changes.
Spring loaded pre-tension on the filament.
This kit uses the original stepper motor that came with the printer and is installed in around 1h.

Installation Tips

Take into consideration the original metal plate that holds the extruder needs to be modified in order to give room for the extruder, this is easily done with a hacksaw and a file.
For simple installation we now supply a custom “Extruder Bracket for Wanhao i3” as you can find in the “You May Need” section of this page.
This mounting bracket is not compatible with the Wanhao i3 v2.1, and it will make the housing to be lower than the nozzle.
If you have a v2.1 (or i3+), you will need to 3D print an adapter to lift up the cooling fan.
You can download the STL from this page.

Additional Information

Maximum X-movement is restricted about 15 mm on the right side.
E-step needs to be adjusted to 140 step/mm (with the LCD panel)
