So, a friend of mine showed me this site yesterday called thingiverse.com – the universe of things.
It's a free database of user created 3D objects that you can download and get printed as physical objects.
I did a quick search and there are several parts for various patrol models that people have made.

I thought this might be handy for some who can't find a specific part or want to make something that's customised.
I only found out last year that you can get objects 3D printed in various materials at Officeworks.
