Bob, gonna try to make it out of clay first and bake it in a toaster oven. If it doesn't fall apart then I will coat it with vasoline and photograph it. Gonna take man's old cupcake pan and fill it with plaster of pairs and stick the grubaholic in it. Don't know what to do next. That is where you come in. What am I doing right or wrong. What suggestions do you have? Should I also place a small tube in the plaster so I fan fill the thing? How do I get it out after you fill it? Could one use a band saw to cut the mold in half to take the prototype out and then fill it with plastic? This might be more than I have experience to handle. I may just leave it to you experts on here.
