Crazy fast and light modular "flamingo legs" stringing tower

Original creator description

This is my take on a "stringing tower" for testing different settings (retraction distance and speed, possibly more like coasting...). I wanted something even easier, faster and lighter than what I had found so far, so I designed this simple modular twin tower (which looks like flamingo legs, also 'cause I was on a pink filament! :-D ). The goal is to pile up as many sections as needed, configure the setting changes based on height and have clear results crazily fast and with nearly no material. The small fatter part on top of a section marks the end of it so one can identify the next section clearly. As an example, I just tested retraction speed on a PLA filament (at 6mm distance) on 5 sec... This hosted file keeps creator credit and Creative Commons CC0 1.0 details.
