Finial for Printer Z-Axis Free 3D print model

A spiral finial for the Z-axis stepper motors of my eMaker Huxley RepRap printer. The base is springy and also fits in the top hole of my plastic spool.

Here's a video of the finial in action: http://youtu.be/5na7NTU9LzI

Fits snugly onto the exposed rod at the top of the stepper motor, so check the diameter is right and adjust to fit (assuming you can edit STL).

Annoyingly I've lost the original OpenSCAD, but it shouldn't be too hard to recreate and improve if you so desire.
