A simple spice rack stair step that uses the entire height of the Core One's Z axis. 

Parametric Customizing

To adjust the model, visit the OnShape document, create a copy and customize away.  

• The shell is step is suppressed, but if you want to customize the hollow version, unsupress that shell step by right clicking and choosing unsuppress.

Printing

I have only printed the solid version as the hollow one may be a little to weak for glass spice jars. If you decide to print the hollow version, please print a smaller cut of just a little bit of it to see what I mean by the strength, maybe it will be better as one big print, but I have doubts.
