I made this print because I couldn't find a sand rammer that perfectly matched my needs. This one is designed to fit on a Prusa printer, and be easily castable in sand. All sides have a slight slope, even the bottom, to make casting as easy as possible. The bottom can be sanded flat after casting however I found that I prefer the slight angle.
This model can be printed at whatever layer height you like, however the smoother the surface finish the better the mold and casting will come out. I printed at .2mm and then sanded, and primed the surface until it was smooth, before adding a layer of spray paint.
In the 1st picture I have the finished aluminum hammer next to the painted plastic model.
In the 2nd picture my model is the one on the left, the smaller one was someone else's model that I was trying out.
