Here's another objective I drew up on my computer. It is supposed to be an Exodite grain silo, though I tried to make it generic enough that people could use it as any kind of Eldar silo/tower thing. It is a bit tall, at over 1.5", but it is narrow enough to fit 2 on a 40mm square base, or three on a 60mm round base. The door is about the same size as the door on GW's imperial objectives.

It is three separate parts: tower platform and base.

I made the base and platform in such a way that I may use them again for different objects, like a sensor tower or power bunker. I still haven't worked out what I want the next objective to look like.

Anyway, let me know what you think.
