Sand Rammer

thingiverse

This is for packing greensand or petrabond sand for casting. As designed it should weigh about 1.8 lbs if cast in aluminum. The alignment pins are 6 mm but could easily be drilled out to 1/4 and then a 1 inch long piece of 1/4 rod could be used. The smaller holes beside the alignment holes are so wood screws could be screwed into the mold to aid in removal from the sand. There's a model of complete sand rammer if you don't want to cast it and just wish to use the 3d printed one instead.
