Show that a litre is a 10 cm cube
A hollow cube exactly 10 cm inside in every direction: fill it with water from a measuring jug and children see that one litre and 1000 cubic centimetres are the same thing, then weigh it and meet the kilogram too.
PETG with solid walls so it holds water; check the inside is 100 mm.
Prints as shown on its floor, no supports.
Filament: at most about 28.6 g of PLA printed solid (roughly $0.57 at $20 per kg); normal infill uses less.
