Here's a quinquereme galley deck plan (and oars) outline at TFT combat scale.

Ambitious.

I am constructing a similar vessel (a medieval galley, like this one), and found that you can save a huge amount of trouble (and printing) by omitting the oars. They are movable and retractable anyway, so having them there only invites complication with rules to address them.

And in your Quinquereme's case, omitting them would mean you could print it with only 6 sheets of paper, instead of 18.
