Find a cool angle
One of the benefits of smartphone photography is its mobility, which means you don't need a tripod!
Move your smartphone freely and find the angle that makes your cool plastic model look its best.
You can just cut out any unnecessary surrounding objects later.
Recent smartphone cameras are highly functional, so you won't notice any degradation in image quality with a crop like this.
