Tamp Hammer
This is a two part blank that when doubled forms a mold blank for casting an aluminum tamping hammer/rammer.
Print each piece twice and sand prep surface with high build primer. glues one of each piece together. Start by molding half of the hammer in one half of a green sand cask. Pin the other piece in and mold the other cask. Cast in aluminum or brass.
Still waiting for better weather to finish my own so this is a work in progress.
There is a great casting video on Youtube showing something similar.
