I wanted a lightweight hook I could take along kayaking that could easily snag a drifting boat. I also wanted something that could use to lift outdoor furniture from ground level to a second-floor deck without carrying it through the house. There are probably many other uses.
UPDATE Version 2 (19 Jul. 2017):
In the original version the tines on hook are brittle when printed in PLA. Version 2 replaces those tines with #6 screws.
The hook attachment is sized for a 1/4-20 eye bolt. One nut is counter sunk in the bottom and the other nut and a toothed washer are tightened from the top to make it solid. Printed in PLA with 25% infill is sufficiently strong for my needs, but I'm not planning on tossing it on concrete.
Disclaimer: No testing has been done to establish a load limit. Do your own testing before relying on a print of this hook. Using this to climb buildings like in the original Batman TV series is particularly discouraged, but if you try it and live, please let me know.
