US Navy's Humble 3D Printed TruClip Design Sent to the International Space Station During Maker Faire
A few weeks ago, we were interested to learn that the US Navy had designed a tiny 3D printed part that, while appearing insignificant, has already saved the Navy over $42,000. The TruClip, created by sailors on the USS Harry S. Truman aircraft carrier, costs about six cents to print and solves an issue that was causing the Navy immense frustration – that of the clasps on handheld radios repeatedly breaking. While it may seem like a relatively insignificant annoyance, replacing each clasp cost over $600, a ridiculous amount for the size of the part.
With such a vast amount of money saved, it’s no wonder that the humble little clip has been generating so much excitement, and not just in the Navy. When the Tru-Clip was created, the Navy agreed to share the design with the International Space Station, and this week they officially delivered it, transferring the files as part of a Technical Data Package (TDP) sent from the National Maker Faire in Washington, D.C. to the ISS. (The files had first been digitally sent to D.C. from the ship.)
Quite a bit of ceremony was involved, with members of Congress and high-ranking military officials in attendance along with representatives from Applied Systems and Technology Transfer (AST2) andMade In Space. If it seems like a lot of to-do for such a small part, consider the implications: this little six-cent clip is a perfect example of why so much effort has been put into establishing 3D printers on the ISS and on ships. Even the smallest replacement parts involve tremendous amounts of money, time and resources to deliver to such remote locations, so something as simple as a broken radio clasp throws a major cog into the wheels of important missions. Being able to print replacement parts easily and cheaply on-site is an accomplishment that has been years in the making, and the fact that those parts can be digitally sent from the middle of the ocean to outer space is even more remarkable.

“Even though these are small steps, it’s kind of a giant leap for everyone,” said Vice Admiral Phil Cullom, Deputy Chief of Naval Operations Readiness and Logistics.
Navy officials were also present at the Maker Faire to discuss the benefits of Fab Labs with attendees. The Tru-Clip was designed and printed in the Truman’s onboard Fab Lab, which was one of the first Fab Labs established by the Navy. The Truman’s lab has also been used to 3D print parts such as oil funnels, switch covers, and deck drains, as well as tubes used by the ship’s anesthesiologist.

“The idea behind a FAB LAB is innovation for the Sailors,” said Gas Turbine Systems Technician (Electrical) 1st Class Rebecca Zickuhr, senior facilitator at MARMAC FAB LAB. “It’s to take the technology we have and put it in their hands so that problems they see every day on the ship and the fleet they can come up with more cost-effective solutions for.”
The TDP containing the TruClip files is one of the first files to be sent to the ISS for 3D printing in space. According to Lt. Casey Staidl, the Truman’s IM-4 division officer and one of the designers of the TruClip, it’s all a bit surreal.
“It’s an incredible feeling,” he said. “This recognition isn’t something you’d expect when you start searching for a simple solution to a common problem on board. It’s a surprise, but a good one.”
