The last time my boys had their Pinewood Derby for scouts, their scout master/pack leader/man-with-more-patience-than-anyone-should-be-required-to-have wanted each boy to walk away with a trophy. A trophy per boy may not be in the budget but some wood and paint were.
Here is a more detailed picture so you can see what went into it.
The top of each trophy stand had a felt pad glued on so the car won’t slide off easily. And, as you can see, it fits the car perfectly. Not only did they get a trophy for the event with their name on it, they got a keepsake stand for their cars.
Such a great idea, I wish I thought of it myself.
