GEEETech i3B/C (METAL version): Extruder End

thingiverse

Human: Hi, Now GEEETech proposes the Acrylic Prusa I3 Pro series B for single extruder and C for dual extruder, with metallic parts instead of original printer ones. Quite immediately I've ordered the upgrade kit to improve stability and quality of my already good printer. Unfortunately, customization designed for plastic version cannot be used on metal one, so I started designing a new customization using all lessons learned from original design! One main lesson learned was decoupling contact points for easy mounting, maintenance, and upgrades. Here's the Extruder End component of my new customization. As you can see in attached picture, electric contacts are now decoupled on top of this component, making installation and extruder attachment a breeze. The decoupler supports: 2 Complete Extruders with power for Hot End, Cable for Motor, and Thermocouple 3 Fans - one always on and two connected to PWM fans if your board has it or Reprap Ramps 1.4 RRD Fan Extender 1 three-wire AutoBed sensor 2 LED You can see in the schema all components needed, and cables are 160cm long to avoid complexity during installation. In the schema images, you'll see how these cables are connected. As usual, I've split design into easy-to-print parts for simple mounting after printing. PLEASE NOTE: decoupler is NOT EASY to create! You must be skilled with a soldering iron! LAST EDITING NOTE: I updated my i3B to i3C by adding the second extruder. Unfortunately, couple of components designed for "B" need small changes to fit on "C": Extruder End - 1: Small change needed for correct operation of MK8 Engine screw Extruder End - 6: Old version was 16mm length; dual extruder requires a 21mm version All "C" components work fine on "B" and not vice versa! IF YOU LOVE THIS DESIGN, PLEASE REMEMBER IT TAKES TIME TO CREATE, DESIGN, AND SHARE... So you can use the "Tip Designed" button on my profile!

For all components, you need symmetrical connector for Arduino side!
