An adaptor may include a shell and a plunger positioned at a first end of the shell and moveable between an undepressed state and a depressed state. The adaptor may further include a ramp extending from a second end of the shell and a carrier coupled to the ramp. In the undepressed state, the carrier may be located at a first position along the ramp, and wherein, in the depressed state, the carrier may be located at a second position along the ramp, wherein the second position may be closer to the second end of the shell than the first position.
