This is my first thing made from scratch. I was inspired by Sharkz created by Muzz64, but found that the Sharkz didn't bite as hard as advertised; And they also lost their bite as you played with them. I wanted to create a better shark. This shark's bite is wicked and will not degrade. Some filing, white grease, assembly required. Crazy Glue recommended for smaller sharks. I also recommend that you start with the large shark before attempting the small one. I have uploaded two versions of the screw. I had no luck creating a good/solid screw with slicer supports, but if you want to try use the "No Supports" file. The Screw file with supports has some small towers that you need to break away before assembly. I also included the OpenSCAD files if anyone wants to tweak it, or make different sizes than the two I provided. Special thanks to Dan Kirshner for Thread Library.
