Nem coupling (Oo model couplings)

These are my most recent design of Nem Hook and loop couplings. like the other couplers, I've uploaded, you mainly just need a paper clip to act as a pivot for the hook. you should be able to use these couplers with already existing models.

This has two versions. one is a copy of nem couplings used on Hornby models and a thicker version as well. I also included Dove-tail fittings and international adapters for both designs.

If you find you facing issues with existing models using these, please comment on the issue with images if possible.
