First off, TheGoofy; you're a genius & I want to say thank you for making this.
It took a couple of days to make all the parts but it looks epic now it's complete.
Getting the screws & rods was the hardest part. I'm still missing most of the screws as I simply cannot find anywhere nearby that sells any screws bellow M3 & had to "long term borrow" some steel pins from work & cut those to length.
Sadly, despite looking awesome it doesn't actually run.
I think this is because of two things:
I printed the entire thing in ABS & I think this results in a less than ideal balance spring.
I didn't drill out the bores through the gears enough meaning they were really tight against the rods.
Definitely gonna have another crack at it.
