Grappling Hook

thingiverse

I engineered this grappling hook to be printed in 4 separate pieces for maximum strength. Make sure the flat side of the hook prints directly next to the build plate. This will necessitate adding supports under the hook and along the threads, but it will align the print layers to maximize the strength of the hooks. Post-processing - carefully sand the flat sides of the threading section to ensure they fit together seamlessly. The nut may be too snug to thread properly depending on your print settings. If this happens, continue to sand the flat sides of the threading sections until the nut threads on smoothly and completely.
