Marklin signpost

This is a copy of the original Märklin 7188 signpost.
The original signpost is designed to hold miniature light bulbs and is switched by a relay
In a modern digital railway setup you don't need the relay any more, and you want to use LEDs.
So, I redesigned the signpost in Blender to hold LED's.
Furthermore, I replaced the wire gutter in the original by a small tube.
The bottom of the signpost is hollow to accommodate the resistor.
