This is a shortened mounting screw for the Logitech/Saitek yoke so that it fits under my table without hitting the keyboard drawer. This is based on Zerink's design, with smaller screw head and a larger bulb on top so that the mounting plate does not fall off.
Note: It will be better to print it horizontally with supports instead of vertically, so that the model has enough strength to tighten the screw.
The author remixed this model.
