Grappling Hook

I designed this Grappling Hook to try to recover a drone from a tree...
The idea was to throw tre grappling hook as a slingshot, grab the tree branches and then shake them...
Unfortunately the day I came back to the park the drone was missing! :(

Good Bye Parrot Swing!

Anyway I was very satisfied with this object, so I decided to upload it hoping that it will help some of you! As always I design really easy to print object.

I've used a 25% filling factor because strong resistence was needed.

In the holes you can easily fit bolts up to 4 mm of diameters, but you can loosen the holes to properly fits event greater bolts.
Use proper nuts on both side to lock the bolts.
