1st of the series OpenLock adaptors Corner Wood. I'll follow with the rest of the series.
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 corner adapter also works with the Spiral Corner Stair wood(http://www.thingiverse.com/thing:2149672) to help match up to the standard E tile dungeon layout or as the second floor penetration. Also the corner adapter is good to integrate into the dungeon E style layout as a 1x1 floor penetration (with a ladder or rope) or standard Openlock 1x1 dungeon fixtures trapdoors, traps, columns etc.
