This is an adjustable bungee hook.

The blue and yellow hook works with a 6mm bungee rope. The black one is a 3mm bungee. Just scale the hook 50% down in your slicer to fit 3mm.

Scale the hook up or down for each type of rope you have.

Choose a rope length that suits you. The rope can then still be adjusted for specific lengths by moving the hook.

If you are looking for a good bungee rope, i allways buy this one: [https://shorturl.at/ijBR7](https://shorturl.at/ijBR7)

The blue rope hook is made of Extrudr PCTG and the yellow one with Prusament PC CF.

PETG would work to but choose a strong filament. 50% infill should be fine.

Here I show you how to thread the bungee. Don't forget to slide the rope clamps onto the rope first.

Now you are done. Hope you like it.

Enjoy.
