Various metal ingots 1Kg size Series 1

thingiverse

These are several ingots that I've precisely calculated to yield approximately 1Kg of material. No factors were taken into account for material shrinkage, so if you use these as a mold for metal casting, you'll want to confirm the weights after pouring and either modify the size of the models accordingly or remove excess material so that it reaches the desired mass. I plan on working further, but this initial series includes Aluminum, Copper, Lead, and Osmium due to their significant differences in volume, allowing one kilogram to be achieved.
