This is a customizable hook with a US standard broom female thread for attaching to a broom handle or extensible rod. I am planning to use this to retrieve some kites from trees.
I recommend ABS.
I made the version that splits the hook in half to avoid overhangs--no support is needed for that--and then glued the halves together with ABS juice.
The hook then glues into a slot on the threaded attachment--also I recommend ABS.
