The tools that i have put together are all types of screwdriver tips, drill, and hammer. The way i have combined all of these tools is by putting the screwdriver tips in the bottom piece (purple). The start button for the drill is the hook located under the hammer witch is the drill as well (Red,Blue,Yellow). The top of the tool is able to turn 180* into a hammer or drill just by pulling the hook out just a little. This tool would be good for the Nasa station and the astronauts.This tool is called The hammering screw drill. You could be drilling something in with multiple drill bits and if needed then pull on the hook and the drill would become a hammer. So this is my nasa multiply tool, The hammering screw drill.
