This is a (crude) remix of the 1x2 stud from educa_thor, or rather it was a starter that I wrapped a 1 inch hex shape around in TinkerCAD.

This base fits into a 'standard' one inch hex grid.

This should print fine without supports; the bottom is solid as it's not intended to snap into any LEGO pieces or plates.
