LEGO brick compatible pantograph

To enhance my MOC brick models of Trains I created a number of custom wheels and other parts which I add here from time to time. Proposals are welcome ...

Pantographs built with standard bricks are too big or too small. Find here my idea to give electric trains a more realistic look. Use a 4x1 plate or equivalent to mount it. The cross parts are not needed. Please note that you have to glue the 3 or 5 parts !
