You just have to know how to help yourself...
A mishap and "too" floating parquet are a certain problem in times of Corona.
I had to take care of the baseboard in a makeshift way, but I was able to do something about the gap caused by the floating parquet: 3d printing makes that possible, too:
Both are just makeshift repairs, but for now, it works fine and the tongue and groove system was great to recreate. :)
