WANHAO EXTRUDER RESTRAINT

This part replaces the cracked or broken black plastic piece that comes with the Duplicator 4. I have been using my printer with this replaced part since Aug of 2014. The Aluminum part will never need replacement again. The cost to obtain one from me is about $95.00. You can reach me at http://www.makexyz.com/store/maker/rspehrdesignfl
You can also download the files and make your own here. I can e-mail you all the files stl and sldprt for $5.00. Simply contact me at rspehr@gmail.com. Enjoy
