When it comes to 3D printing, teams may not exactly need a 3D printer if they want a part printed for use. In regards to 3D printing websites that commercially 3D print a file that you can upload(such as https://www.sculpteo.com/en/, https://i.materialise.com/, etc.), I’d like to question as to why it wouldn’t be considered legal to have non-identical 3D printed items just for wire management.
Also, just for reference:
Functional 3D printed parts are not allowed in the Middle School and High School levels of the VEX Robotics Competition. As stated in this post, we will review the cable management exception for future seasons.
