My part is a multi-tool that can also be a finger splint. It prints with three tools which can be used for dental (or other) purposes, but it would be extremely easy to make different tools the astronauts might need. It can be turned into a splint by attaching the bottom part of the device to the top via the hole in the back and adjusting it so it fits comfortably around the finger. You can use a piece of string or perhaps a rubber band to secure it in place. It can be made out of plastic,but if you wanted it to last longer and for the tools to be more durable, maybe metal would be the way to go.
