Legacy Base Threaded for an E27 Pendant Socket

FritzPeppone has a number of excellent bases for his vast array of globe lithoplanes.

I really like the elegant so-called “legacy base” design that Frank Deschner created. Fritz included a threaded legacy base for E14 sockets (and I couldn't find proper pre-wired sockets that fit these) - I like to use E27 pendant lights and would like these to screw into the base. 

So I merged Fritz's 03_E27_adapter_threaded and Frank's lamp stand.

There are several corded lampsockets that will fit with this - such as:

This adds a legacy base design that allows for screw-in E26/27 sockets
