This hook has been added following recent requests for a 3d printable one.

Some hooks are contained within various wagon models but this one was designed to replace a Northern Finescale plastic moulded hook.
No doubt laser cut steel hooks are much stronger but this hook when printed in PETG has been found strong enough for most applications.
The examples shown are printed in silver PETG (I would normally use black). Infill was 100%, layer height 0.1mm, a brim was included to aid bed adhesion.

Black steel chain was, I think, from Eileen's Emporium who may have ceased trading.
