If you are printing an object that has a base (A statue or trophy, for example), and presuming that you have already optimized every other setting: which shape of base would give you the best and most consistent bed adhesion when using PLA on the widest range of printers (For example, if you're putting it up on a site for anybody to download)?
A square base that is thin at the edges and thick in the middle, and slopes upwards in the center, like a pyramid.
A circular base that is thin at the edges and thick in the middle, like a dome
A flat thick square.
A flat thick circle
Is a shape with corners better, or a shape with no corners like a disc or a fried egg?
Do sloping sides make a difference, or general thickness?
