It's not my style, but I have a suggestion for you. Instead of butchering you cup holder inserts, why not leave them in place when you drill out the base for the LED's? This would locate your holes and you could always redrill them a few sizes larger if you are concerned about alignment issues. Just a suggestion.
Yea, I realised that after I cut mine all up, but oh well, still holds drinks fine.
And I used the cheap little black LED holders.
