Day 15: Stairs to Sketchfab timeframe animation

My first [timeframe animation](https://skfb.ly/6XYCw) got me super excited, and so I decided to digg more, here is another one! Took my [stairs scan](https://skfb.ly/6XUtG) from the other day, made 5 copies, sliced per floor, then overlayed and displayed with our [timeframe animation feature](https://help.sketchfab.com/hc/en-us/articles/203058018-Animations#timeframe). Captured with iPhone 12 lidar + Polycam. I'm trying to post 1 scan a day in 2021.
