Triangulation Pillar (Full Size) Trig Point

This is my interpretation of the Triangulation Pillar as constructed by Ordnance Survey back in the 1940's.
I have used the available information as shown in the attached image from Ordnance Survey.

Where the information is not available, I have interpreted it as best as I can.

This version is full size and is not suitable for 3D printing.
If you scale this down, you will find the clearances between each part is too small.
This model is just for fun. Print the 10% model if you want a smaller version.

I've updated the pillar to include the lifting rings
