For the Mars Medical Challenge, I created a dental multi-tool. It consists of 4 tools that swivel into 2 bars which hold them. A toothpick, tooth puller, dental hook, and flosser are included. The tool would be printed fully out of aluminium. In space, dental tools are needed as much as they are on Earth and having a compact and space-efficient way to have these tools on hand would greatly assist those . Toothpicks and floss can be waste products in space, and my tool only requires a small length of floss to be effective and features a re-useable flosser.
