Ultimaker2 "on the top" extruder mod
This is a mod of the Ultimaker 2 that moves its extruder on the top of the feeder:
It is intended to try reducing the underextrusion problems (see http://umforum.ultimaker.com/index.php?/topic/3261-ultimaker-2-extrusion-problem/page-2)
You have two parts to print:
- The block.stl, this part binds the extruder on the top of the feeder.
- The tube.stl, this part is a guide tube that goes inside the feeder, because the guide tube will now enter in the filament pusher box on the top, and not on the back
