Thanks Forty.
I'll use your suggestion on the next one and move the smallest containers behind the larger ones.
After marking the holes in the board with templates I drilled a starter hole inside and near the edge of the hole.
Then I cut out the holes with a jig saw staying an eighth of an inch from the line on the waste (inside) of the line.
Then I stuck the templates to the board referencing X and Y center lines I had marked on the board and templates. I used double sided tape.
I then used a router with a pattern bit inside the templates to make the holes uniform and clean up the jigsaw cut.
