While designing the plastic components for the AdventureBot, we thought it would be great to open-source the STL files so anyone can 3D print replacement parts.
Print files can be downloaded within the Design tool in ARC (formerly EZ-Builder).
Open ARC, then at the top left, click Open. Click on the EZ-Robot category at the top, and select the proper robot that you're using. You may need to click Not Now on the Open Assembly Instructions popup.
From there, find the My Robot window and click Design.
At the top right, to the left of the Library Manager button, click on the blank dropdown and select the category of part. Find the part, then click on the i button. From there you can choose the STL file to save for printing.
The Design tool also allows community members to upload their own parts to share with the world! What better use for your 3D printer than to make robot parts?
