This easy and great project is perfect if you want something fun to do! Just print the model and use some type of separater like silicone spray to lubricate the insides. Use two M3x20 screws and nuts to fasten the two sides together. Then fill where the feet of the sheep are with hot glue. Note that the hot glue will shrink when it cools so make sure to squeeze as much as possible into the mold. This took me about 1 and a half sticks of medium sized hot glue. Next stick the mold into the freezer or fridge to speed up the cooling process. I left mine in for about 30min. All you have to do is unscrew the mold then use a metal blade to separate the model from the mold. Your done! I personally found that using brittle or moist filament was easier to remove the finished product. This is because the hot glue soaks up the lubricant and then leaves it stuck. Brittle filament later can be easily broken and discarded. The results for my project actually worked surprisingly well! (although it's hard to tell in the picture)

Please show how your sheep turned out and if you have a question or need help feel free to ask!
