OpenLock Adapter-Stone Corner

1st of the series OpenLock adaptors OpenForge 2 Corner Stone. I'll follow with the rest of the series here.
The corner adapter came about, because I needed a 1' wide catwalk/mezzanine and wanted to match the typical A wall on the outside. (thus the "notches" on the bottom to fit the corbel/braces in the corner for the murder holes tiles)

The design became useful in other ways as the corner adapter is good to integrate into the dungeon E style layout as a 1x1 floor penetration (with a ladder or rope) for standard Openlock 1x1 dungeon fixtures trapdoors, traps, columns etc.

This corner adapter also works with the Spiral Corner Stair (http://www.thingiverse.com/thing:2125201 or http://www.thingiverse.com/thing:2125114) to help match up to the standard E tile dungeon layout or as the top floor penetration down to the spiral stair.

Kudos to Printablescenery for creating and sharing the OpenLock standard.
