I picked up some Silicone molds from various places. Since Silicone can withstand high temps, I just used a paint stripping gun to melt some of the scrap to fit into the mold, then put it in the oven at about 400 deg for a few hours. I routinely add more and more scrap as the mold settles until it reaches the top.
Pull it out and let it cool, then pop out the mold and paint if needed.
