The centre of the earth or not?

In all the stuff I have read on how important it is to have a level print bed I have never seen the point as to what it should be level with.

And I have never seen a design that lets you fit the standard 8mm HIFI speaker spiked legs to the printer to ensure the printer is absolutley level before worrying about the bed.

Anyone do this?

The bed needs to be 'level' in respect to the print nozzle. More specifically, it needs to be parallel to x and y axis gantry guide rods.

You can print upside down just fine. "leveling" here is defined as, after homing, setting the distance to the nozzle and the bed and also making sure the distance is the same everywhere on the bed.

For example these backpack ultimakers print just as good as ones on a table:
