Parametric Sieve with OpenSCAD

Parametric Sieve - with OpenSCAD

*** Updated version: now includes optional stacking supports which allow the sieves to fit better if you want to stack them. Six new parameters to play with.
- Added a plain pan to collect the sieved material.
- scad V2.1 is a minor bug fix for z-residual on stack supports
- added more .stl files uploaded including a set of 150mm sieves

Original Notes:
I wanted a sieve, and I had problems running the code in the other examples on here so I wrote this.

I've uploaded a couple of example sieve designs both 200mm diameter so they should fit on most printers. One has 3.2mm holes and the other has 4.8mm holes. If you want any more and you really can't run the scad then let me know. The real purpose of the upload is to share the code with anyone who needs it.

If you're playing around with the .scad features, setting the mesh size to something fairly large (say 10% of the sieve diameter) will render much quicker while you're playing. Set the mes
