I decided to do a Venom pumpkin for Halloween this year and thought that some of Venom's signature pointy teeth would really put it over the top. I couldn't find a good match anywhere, so I made my own.
There are two different fangs- they're very similar but one slants slightly back more. Both have a socket on the bottom of them. A little super-glue should make a good bond between the fang and the post. To insert into a pumpkin (or gourd of your choice), hold the fang in front of you in the desired orientation, rotate the fang 90 degrees along the long axis, push the fang assembly into the gourd up to the base of the tooth, and then rotate back 90 degrees. The locks in the post should hold the fang in fairly solidly.
This was designed to be printed in large groups (I can get about 10 to print at a time without too much problem).
This was my first experience with FreeCAD and my first 3D modelling in a long while (so be nice!).
Print the fangs upright and the posts flat. I used a brim to hold the fangs upright when printing. Keep an eye on it- a few loose/wobbling teeth can cause a mess!
