I noticed ComradeQuiche’s Pendant of Life while looking for something to do with this really nice brass prusament and figured it would be a great print to experiment with virtual extruders for a multicolor print.

Preparing a monocolor mesh for color in Fusion 360

vwacholez added some holes for 2x4 magnets so I used his as a base.

I loaded the stl into Fusion360 to cut out a section underneath the raised sections to be our black background.

• Insert your mesh (stl)
• Right click your project in the project tree and Do not capture Design History
• Open Mesh tools in the Design workspace
• MODIFY -> Convert Mesh
• Right click your project in the project tree and Capture Design History
• Edit model as needed
