What If I Don't Have A 3D Printer?

Not to worry! You can use a 3D printing service such as 3DHubs or MakeXYZ to have a local 3D printer operator 3D print and ship you parts to you. This is a great way to get your parts 3D printed by local makers. You could also try checking out your local Library or search for a Maker Space.

Design Source Files

The enclosure assembly was designed in Fusion 360. This can be downloaded in different formats like STEP, SAT and more. Electronic components like the Adafruit Trinket and Micro Switch can be extracted from the Fusion 360 Archive.

3D Printed Parts

All of the parts are 3D printed with FDM type 3D printers using various colored filaments. All of the parts are separated into pieces to make 3D printing easier. Assembly is pretty easy and straight forward. Use the links below to download the STLs files.

Slice Settings

These parts have been tested and 3D printed on an Ultimaker 2+ and 3 using PLA filament. The parts were sliced using CURA 3.2.1 with the following slice settings.


200C extruder temp
65c bed temp
0.1 layer height
0.22 line width
3 Wall Line Count – 0.25mm nozzle
20% infill
30mm/s print speed
20% Supports

Orienting Parts


The arm and leg are ready to print as is. You will need to duplicate and then mirror the copy of both of them to print the left versions. 

To multiple models, right click on it and select: Multiply Selected Model.


Now we can mirror the copy by clicking on the Mirror icon and then selecting the arrows closest to the model.




The arms and Head will need supports for the overhangs. Enable supports and set them to Touching Build Plate.


Dual Color


The head and torso can be printed with two colors. Load the model and then select the ada-headFace to the second nozzle. Now we can merge the two. Shift select each model and then right click to bring up the Merge Models option. 


Rotate the head so it sits upright. Make sure to have the supports set to Touch bed plate, otherwise the head cavity will generate too much support material.
