Toothpaste squeezer

Push the key through the two holes, it is meant to be tight, and then press the end cap of the key to prevent it from coming back out. Later... It was pointed out that the .stl file had two parts taller than the third, so I've tried to realign and center them on the platform. New .stl uploaded that is, in all other respects, the same as the original. Later still... I reinforced the frame a bit as some people said it was too flimsy. I had also noticed that, while the aluminum tubes work fine, the plastic ones try to uncoil, so I turned the end cap on a ratchet wheel and added a spring to the end of the frame. It seems to be fine, but only time will tell. Use the original key, but use the tpr2 ratchet and tpr2 frame to make the improved version.
