Description
A concrete mold for performing ASTM C1437 according to the design specification of ASTM C230 except that the outer wall have been made extra thick to have similar rigidity as the bronze version. Any high hardness/rigid filament will work.
Although the original document specifies the mold to be made out of bronze (Rockwell B-25), this MUCH cheaper and easy to access alternative works for educational purposes and for DIY / personal research projects.
