Building on Kevin Rau's creations, I am creating an OpenLOCK version of the pillars and arches pieces. I've started with the large arch, as there were a couple of things I wanted to touch up in those files (specifically, the gap fill in the wall sections).
The base tile is 10 mm tall to match the revised Stone Dungeon Tiles (https://www.thingiverse.com/thing:2521474). The total tile height with wall is 50 mm and the long widths are 101.6 mm to match the OpenLOCK standards. I filled the gaps between the wall sections (nothing fancy like brickwork, just a flat fill). I also revised the door to be 25.4 mm wide and 30 mm tall, and made it more flush with the floor for the possibility of a swinging door in the future (in progress).
This is still a work in progress.
09/26/14 - Added small curve 2x2 corners
09/20/17 - Added 4x2 end cap
09/09/17 - Fixed the brickwork mesh. Heightened the walls to 40 mm (50 mm total height). Base tile is still 10 mm height.Added stone tiles on which the base is built.
09/10/17 - Ran another repair on the files with Microsoft 3D Builder. I was having a minor print issue, but it appears to be corrected now.
