The file '12-Sided Tower Accessory – Bridge Stairs 3D Printer Model' is (STL) file type, size is 362.5KB.
This is a staired bridge that crosses the span of two towers (about 6" apart) and one floor in height. I've printed a prototype already with custom supports. I've added my latest version with and without supports. I will post a make once I get to print the revised version.
EDIT: 7/3/17 - Modified the stairs so they can go from the base level to the second story. The original is good between upper stories, but the ledge under it is too high for the ground floor.
EDIT:7/7/17 - Added stair base for stairs that go to ground level without connecting to anything.
