I've been casting about for the overall diameter of the Phoenix footpads. I have found some notes but they do not gibe with other info. I think the overall footpad diameter is 315 mm, based on the hydrazine tanks being 420.1 mm in outer diameter.

Can anybody help a model builder?

A quick search (size+footpad) on the Phoenix threads highlighted these two posts:

This paper has two excellent top views - one of the science deck and one of the stowed arm. Used them to make my own 3d model...

Thanks to all! Looks like 292 mm is the right size.
