Helical slide rule / pencil holder

A true helical slide rule in the tradition of the Fuller and Otis King calculators, but just a plain slide rule bent into a helix.

On my Creality Ender 3 V3SE, the base prints fine without supports, but the coil definitely needs them. The scale and numbers are pretty small at this scale- you may want to scale everything up, especially if you intend to color them like I did with marker (it didn't work great for me).
