Nice idea, do you have any prints from before vs after applying this mod? Did you notice any change in print quality or artifacting?
Was this mod purely to reduce the overall shaking of the printer for noise or general vibration of your table issues?
Thanks.

That's interesting... I see you did not removed rubber legs. Is it better with them or without?
Also would appreciate if you share photos of some test prints with and without concrete plate and with or without this strap.
