FINISHED BUILDING FIRST 3 STAGES. As you can see, the first stages are already taller than me. I am bout 5’7. There will be 10-12 stages to reach 2 floors the retracted length is about 25.5 inches. As for cad, I am done up to the 6th stage. (Yes I’m building in the closet) sadly the decoy won’t let me post the video of it extending but it is around 6’4 I would say
