Modicum Extruder - New belt drive extruder design.

I designed my first geared extruder with premade fine gears. It gave me basicaly no lash, however the slanted gears are really beating up the bearings. The design also had some precision problems. I am still using this extruder at this point but hope to replace it with my new design once I get it right.


I wanted a belt drive extruder that would be small and have easily attainable parts. The next mission is that the extruder body should be easy to print (I failed at this part)


Here is the preliminary design. If it gathers interest I may do a run of these small extruders at some point once I get the bugs worked out. For now I am going back to the drawing board.


Here is a video of the extruder being built. http://youtu.be/6TIUHaaqH7Y




Here are some images of it as well.
