Parametric twisted star box

Parametric twisted star box by rhmorrison Aug 19, 2012

Description

I liked the twisted star box (which is also parametric) but it requires not only Art of Illusion but also a special under development and undocumented MetaCADEvaluator plugin that is part of the development version of CSGEvaluator for Art of Illusion:
objects.reprap.org/wiki/Builders/Metalab/AoI_CSG_Evaluator

and since I wanted a box with very specific dimensions I decided to make a version using my tool of choice - OpenSCAD!

File size < 3k instead of 12k! :-)

Mine came out perfect.  The ridges left behind by the layer height steps makes for a nice fit.  nice job!

 Then increase the value for tGap and only create the top, save as STL and print.

The lid wont fit here ..

Instructions

There are three primary variables:
1. the inner radius (i.e. the size of the hole),
2. the wall Thickness (used for top, bottom and lip) and
3. the star box Height (the height of the box w/o the lip/top).

The remaining variables:
sbLip, tFactor and tGap can be changed if desired.
They are documented in the SCAD design file.

I'm still printing mine, will post the final result when it's done. Your's is a lot smoother than mine. Mine has these lines that travel up diagonally through the whole box. But it's consistent... it's not random so i don't get why it's doing it.

It may be due to the smaller layer height or an artifact of the slicer used.

Does the top fit well to the body?

What slicer are you using and what layer height?

I used Skeinforge and a layer height of 0.4mm.
