There is a learning curve on using new tech, so one should not expect everything to work perfectly the first time. :-)
We can make the base and float merge together so it is a stronger connection.
We can have the heating pad go off after the first few layers, which might make them harder and less wobbly. We can have a honey-comb structure inside so it is not just hollow. There are lots of other things to try as well. Of course printing a smaller object should help.
We put the printer at work for several reasons. There is more free room at work. There is a cat at home that I could imagine attacking the machine or scratching it or at least getting hair into something. It makes noise but in the office it is far enough from where I work not to bother me. Also it seems a fun window display that people might find interesting. However, we may need to set up a web cam so we can check the progress of 3D prints from home.
