Introduction: Super Replicator 2
I wanted to 1-up my Replicator 2 with a Super Mario inspired theme!
Aside from the blue paint used on the panels, all of the pieces were 3D printed and not painted or finished in any way, the multiple colors are from swapping filament colors mid-print.
All STL files for this project are available on Thingiverse here: http://www.thingiverse.com/thing:1486365
My general process was:
- Trace features from reference image using Illustrator*
- Import the SVG file of each feature into 123D Design and extrude each piece to create 3D models.
- Print all pieces, pausing mid-print to swap filament colors (this part was intense!)
- Paint the panels, glue the pieces, and assemble everything!
Keep reading below for my full process of creating this!
*NOTE: I used Illustrator because I have access to it through work. This same process could easily be done using a free alternative such as Inkscape.
Step 1: Find and Import Reference Image
A quick google search of Super Mario Level 1 gave me this reference image, which I pulled into Illustrator for tracing.
Step 2: Trace Features Using Pen Tool
I manually traced out the major features that I wanted using the pen tool. I put each on separate layers so I could toggle them on/off and for easy export later on.
NOTE: I don't know anything about Illustrator, and I'm sure there is a much faster way to do this.
Step 3: Export SVG's and Import Into 123D Design
I exported each feature individually as an SVG file (I tried to do it all in the same file but 123D Design wasn't happy about that).
In 123D Design, I chose the "Import SVG as Sketch" option.
Step 4: Extrude Features to Correct Height
I knew I wanted to swap filament during the prints to achieve the multi-color look, and was able to match each color from the image (closely enough) to a MakerBot filament color (each feature has no more than 3 colors).
In order to do this, I extruded all parts of the model to specific heights based on their color.
See the brick example picture:
When making the model, I extruded the Black sections to 0.8mm, the Light Brown sections to 1.8mm, and the Dark Brown sections to 2.8mm. That way (when printing at 0.2mm layer height), I could start printing in Black filament, pause 1mm, switch to Light Brown, pause at 2mm, switch to Dark Brown, and complete the print.
Step 5: Print All of the Pieces With Z-pause
I grouped together parts that use the same color combination and printed plates of each part (see attached chart of color combinations).
For each print the process was:
- Start print with base colorSet Z-pause height to 1mm
- Wait until print pauses at 1mm, switch filament to 2nd color, resume print
- Set Z-pause height to 2mm
- Switch to 3rd (final) color and wait for print to finish

Note: I way overestimated how many pieces needed to print, so if you are following along on the spreadsheet you should adjust the quantities of each part.
Step 6: Paint the Panels
I removed the 3 panels from my Replicator 2 (front and 2 sides) and prepped them for painting - removed the front stickers, lightly sanded the front surface of each, and wiped them all down with rubbing alcohol.
I tried to match a spray paint color as best I could to the background color, which is how I ended up with Street Marking paint, but it seemed to adhere just fine to the panel surfaces.
I used 4 or 5 light coats to make sure it was an even coating.
Step 7: Layout, Glue, and Assemble!
Now the fun part! I originally wanted to lay out the pieces as an exact match to the original image, but I ended up having more fun just laying them out a few different ways to see what looked best.
Once I settled on a layout, I used hot glue to stick all of the pieces in place.
Finally I put the panels back on my printer, made sure everything stayed in place, and got back to printing!
