OpenForge 2.0 Mag + Door Full Spiral Stair

OpenForge 2.0 OpenLock 4
This is an exercise!. I do not know how this will print. The goal was a full corner staircase roleplaying terrain feature/accessory to depict a full tower and doorway tile. Recreated the spiral stair effect by xloud - Spiral Stair Up (if you notice, different treads). Set for OpenForge 2.0 (25.4mm sq tile) and able to glue to the standard E OpenLock base, or MAG base.
