Bondtech Style Extruder

Description.

 

Made up this Extruder shell for my recent Creality Ender 3 purchase to replace the stock extruder.

 

This Bondtech extruder gear housing was designed for 12mm press fit fittings i had purchased from aliexpress,  the housing also uses an M3 square nut for the tensioner instead of a brass insert.

 

The body is slightly smaller than the original it was based off of, and the filament path is a bit tighter.  The Inserted PTFE tube also goes further into the body on both sides.

Hopefully it may come in handy for somebody.

For the Bondtech gears you have the Original gears from Bondtech which would be the preferred option.

But as always there are now clones available which may also work.

The choice is yours but it is always preferable to support the actual original designers and developers of a product. But the choice is yours.
