2D Attitude Indicator keychain fidget

Quite a mouthful innit'. 

I made this model originally for my friend who recently got his pilots license (may god help us all). 

A attitude indicator or “artificial horizon” is a piece of aviation instrumentation that helps the pilots to determine the planes orientation relative to the ground. Pretty handy if you're in pitch dark night or a storm!

It's a 2D attitude indicator, so the fidget wont tell you if you're in a climb or nose dive. It's rather delicate and can still keep up even if not rested on a perfectly vertical surface. I personally had the pleasure of testing this in a real plane while on a work trip and it was fun watching the degree of turn while taking off!

The model is currently only for AMS, but i might take a stab at making a version that doesn't need a AMS.

The model does require some hardware, all linked in the BOM. 

I also tried using a thin clear screen i got from one of those ikea picture frames, it does seem to add some class to the whole thing, but isnt strictly necessary. 

***************HOW TO*****************************

   2. Start by inserting the bearing and steel ball into the dial

   

   3. Insert the steel rod into the inner shell

   (4.5 I cut out a small acrylic sceen piece and placed it inside)
