Hook

here is a simple but useful hook that can be used in your keychain or to hold stuff, i took few with me while bakcpacking and it was quite useful. 

It will hold at least 20 kg, it could hold more but i have not tried. 

it measures around 4.7cm tall, and around 2.7cm wide.

I have used this on my keychain and it has hold pretty well, as you can see it has guides at the edge which will help keep the two side of the hook in place, very resistant.

I have printed this in PLA but I think it can be printer with other materials too.

Instructions:

As soon the print finishes, the bit where the ends of the hook meet are stuck together, push the hook as if you were opening to add your keys and it should just detach, don't worry you will not break it :)

Ask if any questions.

Thanks
