Grappling hook, Or chain
thingiverse
The 4 mm nozzle appears to function well, allowing for use as either a chain or grappling hook. To create a longer chain, simply print additional segments of chain, then bond the severed ends together using adhesive. If you wish to incorporate a grappling hook, attach the partial chain to the existing hole and secure it in place with glue. Ensure that all printed components are fabricated at identical scale dimensions.
