OpenForge 2.0 Spiral Stair with Wall (ORIG) OpenLock Base

OpenForge 2.0 and OpenLock
A roleplaying terrain feature/accessory to depict a spiral staircase going down within a wall. The first step is a trip hazard, as OpenForge has thicker floors, the first tread is a little high, but serves to provide that roleplaying feel for a set of stairs going down (grinds against the OCD mind). Quick cut and paste and still could use some cleaning.
