A project that has been asked after of me for a while is a freestanding staircase, in this first application from a main table level up to a raised platform train station. The grade change will be 5-11/16", the overall run can be about 8" and the width will be 2". There will be a landing at the halfway point and at the top. I plan to use EMA Plastruct structural steel shape for column supports . The railing layer will be .060" laser cut acrylic. The stair riser layer will be .125" laser cut acrylic. Risers will be open and treads will be 030 x 188 Evergreen Styrene.
