gravitational hook with snap fasteners

My son asked me to make a crane for him to play with, and so I set around looking for a hook and found Snorri's gravitational hook. I printed it straight away at 200 % as an awesome toy BUT couldn't find any M5 machine screws (thanks Covid Lockdown!) so I tweaked TZT's fastener design to suit.

Hey presto - a quick and easy to assemble and entirely 3D printed gravitational hook. I also opted for only 2 hooks rather than 3 - just out of personal preference.

The fasteners are designed to be loose to make the mechanism move freely.

You will need from snorri:
GH_bar - qty 3 printed at 200 %
GH_Hook - qty 3 printed at 200 %
GH_attach - qty 1 printed at 200 %

from here you will need:
M5_clipnut - qty 4
M5 x 9 - qty 2
M5x13 - qty 1
M5x22 - qty 1
