Model Stairs for Train Layout

thingiverse

Customizable stairs for your model train layout. I printed these in O Scale (1/4" to the foot) for my toy train layout. Set CreateSTL to "Display" for SCAD to display the stairs as 3-D stairs. Set it to "Print" to create a flat layout that can be exported to an STL file and printed. Then it needs to be glued together. Some combinations of setting the physical parameters of the stairs may not be buildable in the real world, and some may crash the OpenSCAD program. Stair values from this web page: https://www.calculator.net/stair-calculator.html Use the "Comprehensive Version" of the Stair Calculator. This program is capable of building every stair possible. I believe that if you always make the Total Rise equal to an integral multiple of the Rise, the program will be able to build the stair. Enter your values into the equations on that web page. Select the "Use One Run" tab. Set "Fixed Rise", "Has tread", "No headroom restriction", and "Standard stringer mount". Also enter values here for Run, Total Rise, Rise, and Tread thickness. Enter a Thread thickness of 1 inch. Then press "Calculate". Enter the Results from that web page into this script's customizer. You may have to re-enter the Rise if the calculator could not work with your suggested Rise. The Stairs OpenSCAD program does not need every Result value.

G scale stairs may not fit on a typical build plate, and each part of the stairs may have to be printed individually. When you select the "Print" option, the stairs are disassembled and laid flat. You get two stringers for the sides with a support for each tread, X treads depending on the length of the stringers, and one railing. Some assembly required.
