All pictures of makes were printed at half the size as the stls you can download. Just scale them down in a slicer for similar sized prints.
Update: We made a solid lotion bar with the snowman mold and recipe included https://www.youtube.com/watch?v=K9OTnMV3-Ys
Update : So we decided to create more things with the molds. So we created a candle snowman and two plaster snowmen. You can watch our youtube video on the whole project. https://www.youtube.com/watch?v=eO9M_CSkRq4
This was done for the remix challenge on thingiverse I decided to remix the Snowman maker by CloudJ https://www.thingiverse.com/thing:675620. I simply made the mold so it could be used for pouring. By adding a pouring hole and two small air venting holes to try and keep spit-up to a minimum. We decided to use some melt n pour soap as our pouring material. Above you can see some pictures of our results. We added some things like eyes and buttons after removing them from the mold. Our video goes into more detail and shows the actual pouring https://www.youtube.com/watch?v=EqdEFHgNMc4&feature=youtu.be
I tried to keep the molds the same size as the original and have the other items fit that size.
