You would be wise to design for Serviceability and Manufacturability as many of the previous posters have said. It doesn't matter if you have the best design if you cannot manufacture it correctly or it takes too long (and you don't finish). It also doesn't matter if you have the best design and when it breaks, you can't fix it in time for the next match. I have seen a particular powerhouse team with deadly accurate scoring mechanisms sitting dead or only being able to play defense for multiple matches at multiple off-season events this year.

Think about how each part will be installed and what tools will be needed and how those tools will be used. Think about which parts you will need access to for servicing and what tools can be used. Are there parts that must have some exact dimension(s) to fit properly? If so, you may be setting yourself up for a lot of frustration.
