I had been looking at the off the shelf kits for making a replica of your member and always thought they were overpriced and you could only make one mold. So I took a trip to the hobby store and researched a bit. Without buying any expensive lifecasting supplies I was able to make this plaster replica of my penis for $20 ($10 with coupon) using safe non-toxic casting gel and then plaster for the pour which was also included in the kit. I figured I would share my creation since I think it turned out very well for a first attempt. I have attached a couple pics. After the plaster has fully cured I plan to make a more durable latex mold and do a few silicone clones for some friends and for gag gifts.
