A rigid wire must be connected to the float. I used an old coat hanger. Add a cork to the base.
To attach the various components together I used a 3d pen. If you don't have it you can use glue.
Inside internal vase I inserted expanded clay. Alternatively it is possible to use potting soil.
I did not print the ceramic vase as I owned one. Is a common orchid pot.
I do not recommend fixing the funnel but inserting it as necessary.
