The cylindrical tower base is the first assembly. I cut off the sawtooth tabs from the ends of the cylinder; I find that these hinder the ability to get a nice smooth circle. I also cut off the vertical connecting tab and instead used 110 lb cardstock to create an inner cylinder and allow for an end-to-end closure of the cylinder instead of the tabbed overlap.
I wanted to make sure the cylinder was sturdy and maintained a nice circular shape, so I cut three formers out of 1mm cardboard— one for each end and one in the middle. I made smaller support cylinders out of the 110 lb card. I’m pretty happy with the result. The tower base came out round and smooth, and fit perfectly onto the base.
