Triangulation Pillar (10%) - 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.
This version is 10% of the full sized Triangulation Pillar I have modelled.

Where the information is not available, I have interpreted it as best as I can.
I have adjusted all of the clearances compared to the full size version to allow for 3D printing.
Hopefully these clearances will be OK on all suitable printers.

Each part can be printed individually as required.

I've added a version of pillar that has the lifting rings added.
