--------

This is a hook tool to assist in opening doors
(inspired by [Coolioiglesias' Savegrabber](https://www.thingiverse.com/thing:4192643) , though it uses no part of its design)

It is modeled with a manual flip-open action, similar to a swiss army knife.
When closed, the hook is mostly enclosed to minimize chance of transferring contamination.



**Features**
-------------------
Measures 106mm x 55mm x 23mm (4.2" x 2.2" x 0.9") when closed.

The hook accomodates:
- Round handles up to 33mm in diameter
- Keypads with keys as small as ~6mm
- Lever handles, in general.
- Those push-flap and push-bars things on doors, using the V-groove on the tip.

Hook is not designed for round doorknobs.

Press the button to unlock the hook, which can be flipped open with a flick of the wrist. Do the same to close. Button locks the hook
