The cup holder attaches to the side of any AeroCreeper. Print your own with the attached .stl file.
Printing tips: Print in the upright position. We abandoned putting support material under the bridge since it worked well without. Good adhesion is important so the "handle" doesn't tip before it's connected to the cup. The .stl file is in inches. If your printer runs in mm, you can scale the part by 2540%.
