After having issues with the original multipart base that was bolted together not being stable enough, I chose to make this base that I can use to bolt to a sturdy 5Gal Bucket Lid. I made 2 parts just in case more support was needed on the other side of the bucket lid.
Just cut a hole in the bucket lid or other cover material that is the same size as the hole in the flange (Flange can be used to trace the hole onto the lid) → drill holes for the bolts in the lid → bolt flange to the lid → attach your tower segments and get to growing.
