To create an open source pellet extruder for an open source desktop 3D Printer.

Background

Problem Statement

Project Significance

This tool head once complete will be the first Lulzbot compatible FPF-style extruder assembly.

Project Goals:

1. Design a tool head that can be used on a Lulzbot Taz 6
   • Design uses components found on a standard Taz 6 tool head
2. Cost of toolhead less than $400

Future Goals:

1. Tool head design adopted to other open source desktop 3D Printers
