Summary

This is a hook to implement a hook and chain coupling as used in British and similar rolling stock. I haven't tried it with a chain yet, so it might change per feedback and use.

There are several commercial hooks and chain couplers available. This was designed by eyballling some.

The peg is 1.2mm (.047") diameter. A hole to fit needs to be done on the end cor your car.

This should be able to be scaled up for O or large scale.

Edit: Work in progress. two files added coupler hook2 has the hole enlarged .1mm. Chain test 2 is a first try at a chain. I haven't tried it yet so I don't know if length is good. When I tried printing it with a .4 nozzle FDM it printed but was too fragile to reliably clean up. I successfully printed hooks and chains on my Elegoo Mars at 40um layer height. This is probably too fiddly to operate, but should look nice for a static model.
