HOrnby-acHO " Standard nylon " couplings

I have always found these HO couplers very practical because they allow to extract vertically a car located in the middle of a train, and on the other hand, aesthetic because the space between cars is reduced compared to the loop couplers. So I gradually replaced the loop couplers on my HOrnby-acHO equipment with these couplers. Over the years several types of screws were originally mounted to hold the hitches of the HOrnby acHO equipment; these screws are different because the centering located under the head is more or less long. So I created 2 depths of counterbore to accept these different screws and avoid adding a washer. And a friend suggested me to go further by reducing the space between the cars. Indeed (see photo below with the original couplers) the position of the coupler in relation to the buffers is not the same depending on the car! Each coupling is marked by an engraved number, the odd numbers are with a deep lamage the even numbers with a shallow lamage." So the download has 8 stl files. Numbers 1 and 2 are 1mm longer and are intended for materials of other brands. Numbers 3 and 4 are the same length as the original "Standard" hitch. Numbers 5 and 6 are 1mm shorter and are generally adaptable on bogie equipment except Mistral stainless steel. Numbers 7 and 8, shorter by 2mm compared to the "Standard" version, are rather for axle cars. The previous choices are indicative and related to the radii of your curves Rev A : addition of 2 .stl models
