The parts are optimized to print with dual extruders and no support material. They're oriented in the center.

This project was prototyped using the Flashforge Creator Pro.

Customize Design

You can modify the original solids in the CAD files to make a custom project. 

Materials

The conductive parts can be combined with different types of filament. The most common filaments like PLA, NinjaFlex and ABS will do just fine but you can of course experiement with copperFill, bambooFill, Semiflex, PET and Nylon. 

Clean up

If there's any string or artifacts left over from the ooze shield, clean up the part by trimming them off using a pair of flush snips.

Dual Extrusion Setup

To setup your slicer to print with dual extruders we'll have to first align all of the models. We used Simpliy3D, but the process sould be the same in other slicing programs.

After importing all of the stls into your project, align the model origins under: Edit > Align Selected Model Origins.

Group models

Next we'll have to place all of the stls flat on the bed. To move the objects as one, we'll have to group them together under: Edit > Group Selection.

Assigning models to each extruder

Now we'll need to tell each extruder which object to print.

Use the dual extruder wizard under: Tools > Dual Extrusion Wizard to help set up your extruders.

Color 1 is the Right Extruder

Color 2 is the Left Extruder

Verify tool path

Preview the tool path for each extruder by selecting the Active Toolhead option under the Coloring drop down.

Tool 0 (blue) is the Right Extruder

Tool 1 (green) is the Left Extruder

You'll want to make sure that none of the colors overlap each other or the traces will not have a complete path to pass along power.
