And we have a tower! It is made of foam, cut on my Proxxon with guides that I designed and cut out on my Silhouette. I assembled it and added the chicken wire as rebar, then a coat of spackle/wall compound. It will eventually sit on a 6x6 Open Lock 3D printed tile. The tower is ~10 in tall, not including the 7mm of the base (which I'm not counting, as it is just that - a base).
