Extrusora Prusa i3 Modificada

I modified the extruder head to use it because I've noticed two major improvements:
1.-The motor can be blocked by the pressure of the gears and not function properly. So I've modified the holes in the nuts so they can have some slack.
2.-When the ABS is blocked, it is very difficult to remove the head, so I've removed the small support holtend guide to make it easier to replace or clean.
And that's all .. I hope you like the idea.
