Giá đỡ ống nghiệm kiểu Voronoi - Parametric

This script lets you generate a Voronoi test tube rack. 

If you've never used openscad before, here are some basic instructions to get you started.

1. Download fastvoronoi.scad and test_tube_holder.scad into one folder

2. Download and install OpenSCAD

3. Open test_tube_holder.scad using OpenSCAD

4. Edit the first few lines of the script. The comments explain what each variable does.

5. In the menu, press Design > Render

6. In the menu, press File > Export as STL (ascii)

You now have an STL file that you can bring into a slicer to print.
