Hey Fred, I didn't know about the existence of Stud.io (my bad) and LDD was kinda hard to use so I skipped it. But thanks to your advice I managed to build a Stand on a 16x32 baseplate that is based on your design on Stud.io.
Here is what it looks like from the back, I only added 9 small pillars for stability of the structure. Looks a bit like a stadium stand in high schools though.
Would really love to hear some comments for improvement from the creator of the original design, many thanks Fred.
