Summary

This Parts allow to move the extruder from the Print Head away to somewere else, to reduce the weight of the printhead. This has greatly improved print quallity on fast direction changes of the printer.

Instructions

This consists of 3 Parts.

The Replacement Part for the Extruder on the print head
The Mount for the tubing on the extruder of the printerbot
Optional: A mount for a 40mm fan that keeps the upper part of the hot-end cool. This is optional, works perfectly (tested on 8 hour print) without it.
Used a spare pressured-air tubing to connect the extruder to the hotend.
You will have to drill up the whole a little bit. Used M3 Screws and Nuts to lock everything in place.
Note: I had to oil the inner side of the tubing as otherwise the friction was too much for the motor.
