Improved Points motor with indicators

Sept 2019: I have published an "Improved Improved" design. (https://www.thingiverse.com/thing:3883510) this is a major redesign with the rack now mounted "under" the servo. I have also modified and simplified the indicator.

I will leave this Object here for reference or if you need to print spare parts. The indicator parts should be interchangeable with the new design, but all other parts have been modified or re-drawn.



Comments from earlier versions...
There been comments about the pinions and servo fit:
My three gears (s,m,l) are supposed to have holes (hex holes) 3.9, 4.4 and 4.8mm flat to flat.
I discovered that I had two types of ES08MAII servos. -- presumably one is fake? --.
One has 4.7mm pinion (and is 11.9mm thick) , the other 3.9 (and is 11.6 mm thick) .
My examples of ES08DE have plastic pinions of 3.8 and are11.7 thick.
I also use TGY9081MG , with 4.8mm pinions, which is 12.2 thick and a bit longer, but the pinion to flange dimensions are the same so
