I'm working on a few iterations of spiral staircases in scale, and I created a simple version to test before venturing on to more complicated projects.

This version is in 1:24 scale. Sixteen treads are required to complete a 360 degree revolution. The rise is 9".

I have some landing options I plan to upload in the near future.


As formatted, the STLs create a Left-Up staircase. Mirror files if you desire a Right-Up version.

Print as many treads as you require, plus a base. Treads are designed to thread onto a bamboo kabob skewer, or other rod 3mm or less in diameter, but this is not required. Snap treads into one another - the snaps are offset to maintain correct spacing between treads. Use acetone for permanency, though the pieces hold together well without an adhesive.

I love it! 1:24 scale, 9" rise (which is against code in my area), and you know what a landing is. You speak my version of English. :) Very nice design... well thought-out, and you obviously know building.

Would fit right in with my 1:24 scale collection of architectural models posted on Thingiverse. But my house doesn't have a spiral staircase. They're nice to look at, but a pain in the buttocks if you ever own a set. Very awkward, and try moving any piece of furniture up or down a spiral stairc
ase. Forget it! :)

All of the homes I design have 4'-0" staircases. I'll go 3'-6" if the homeowner absolutely demands it. :) And then I whine the whole time the home is being built. ;) Heh heh.
