Answered: 3D Printed Wire Clip

Is it legal to use 3D printed wire clips for wire management? The rules that are referenced by this is R7b and R7l. We were debating if it is legal because the 3D printed version is identical to the ones sold on the VEX website. Also, the wire clips are commercially sold, and they are not functional parts of the robot (only for wire management).


b. Any parts which are identical to legal VEX parts. For the purposes of this rule, products
which are identical in all ways except for color are permissible. Note: It is up to inspectors to
determine whether a component is “identical” to an official VEX component.

l. Commercially available items used solely for the purpose of bundling or wrapping of 2-wire,
3-wire, 4-wire cables, and pneumatic tubing, for the purposes of protection, organization, or
management are allowed. This includes but is not limited to electrical tape, cable carrier,
cable track, etc. Note: it is up to inspectors to determine whether a component is serving a
function beyond protecting and managing cables.

While we admire your creative solution, no, these would not be legal for competition use.

Regarding R7b: 3D printed parts are not considered identical to legal VEX parts due to differences in material type, strength, or other physical properties. Please see this Q&A.

Regarding R7l: These are not considered “commercially available”, as they are being designed and fabricated for individual team use with equipment (3D printers) that not all VRC teams have. Please see this Q&A.
