A few options…
If you have a single object, select 2 diagonal points on the base (or the lower face of the base if you’ve not already deleted it) and run my ShiftCentre plugin (or operation)
There is also a ShiftGroup script on my website that lets you enter a value to shift a group axis.
Lastly, you can do it by eye – select the Shift tool on the right, hold down the Ctrl Key and Right mouse drag the Axis down to the floor level.
