I know the rules state that we can use any parts that are identical to official VEX parts. Does that include parts that we can print at our school with a MakerBot that the CTE department has? It makes the parts out of plastic that is very similar to the plastic that VEX gears are made of so I would assume that they would be legal since they are identical.
Just to save you the time of looking, the related rule states:
“R7.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.”
