The excellent Turnigy hex key set comes with one metal handle (on left in picture), which is find some of the time, but if you find yourself changing keys all the time you can print more handles. This object was made in Tinkercad, and printed in Amazon Basic PETG on a Prusa 3. The hex key just pushes in and is gripped tightly.
