To start off I want to give props to jamundsen for his hammer, this is a modification to his hammer. I felt the need to make it a new post because I added several mods.
The hammer's body and face plates can be printed at without support. The rings were printed with raft to ensure flatness, I used a silver Sharpe to color in the groves of the rings. and used a strip of leather for the wrist strap on the end. I used a light metal pipe i had laying around for the center of the rings. the pipe runs the full length of the hammer and i used sand to fill the hammer up for weight. I drilled two fill holes on top of the hammer to funnel the sand in and used the top cap to close it off. the hammer came out to be 10Lbs.
