The space clamps are a tool that can be used to secure objects in a zero gravity environment. One side can be secured to a tool or clipboard, and the other can be secured anywhere you need it, be it an EVA workstation or the interior of the ISS. The tool is essentially two clothespins that are attached with a ball and socket joint that has been optimized for 3d printing. The clamps are designed to be easy to be used even with the thick EVA gloves. These are a good choice for something to be 3d printed, because a tool like a wrench or a drill should be very high quality, and you really don't need more than a few drills at any time. Something like clamps however, you can print out as many as you need or want!
