Pellet Extrusion Stirrer

30/12/2018 Added a bracket to hang the funnel from. 04/09/2018 I released my marlin configuration for using an extra stepper and driver for stirring, check out our discussion here: https://www.thingiverse.com/groups/universal-pellet-extruder/forums/general/topic:31110#comment-2024531 Also see ideas from the reprap community here: https://reprap.org/forum/read.php?1,831119,831229#msg-831229 This stirrer prevents feed stock from getting stuck on its way to a pellet extruder. I built this because I found that recycled feed stock gets stuck easily as the parts are high friction. My goal is that this can be used with any pellet extruder. Printed in PETG 35% infill and the head printed in Carbon Fibre PETG 100% infill. This is made to work with a 155mm diameter funnel. However, the FreeCAD file is included if you need to change it. There's plenty of room for improvement to print with less material, add a slider to work with a geared DC motor like an N90 instead of a stepper and make the adjustment easier on the motor height. However, this is already from my point of view a working design. I'm using it with a Mahor Pellet Extruder V3 and my own designed feeder and hosing which you can find here: https://www.thingiverse.com/thing:3032188
