#649 Adjustable Stair Steps

[MrJaw]

I made some stair steps in Blender. They conform to real world dimensions, and each step can be made invisible to more closely accommodate a variety of needs.

The texture comes from Joao Paulo, available under CC0 license from https://3dtextures.me/2021/02/15/wood-plywood-001/

Hope somebody gets some use out of 'em. :)
