Yes, the tower is growing. I decided to continue the construction of the LUT virtually, because I flirt with the idea to make it dismount-able. The background is the portability.
Assembled, the thing has a height of about 160cm, and is therefore a bit bulky to transport, not to speak from a secure packaging once completed. But to make the LUT dismountable, I need a halfway finished model to define the breaking points reasonably.
LUT Level 30
The construction everyday life sometimes strongly rocks my knowledge of geometry, so the inner diagonal struts are diagonal in all space dimensions, which does not represent a problem for the cylinders, but very well for their 'landing zones', whose plates want to be constructed in the correct plane, which is by no means trivial.
Also for the mass of the plates a deep look into the handbook of the American Institute of Steel Construction was necessary again, along with pertinent hints from experts - the NASA plans are limited to construction hints without giving details.
LUT Level 30
Even though the tower still looks very puny from a distance, a closer look reveals a certain variety of details. The stairs cost a lot of nerves, because the thing didn't fit by 2 inches, until I finally discovered that the stairs are offset in horizontal direction by just these 2 inches against each other. Yes, you have to watch like a hawk. Another thing that hard to recognize was their handiness - for a while I had actually installed the stairs mirror-inverted, which becomes apparent not before Level 80 and leads to problems.
I'm also worried about the railing. Here, cut acrobats can look forward to a new level of self-realization. The topic lasercut knocks very lastingly in the back of my mind ;)
