Please visit OpenSCAD.DIY3DTech.com for more information on this and many other projects! As in this episode we will be looking at using Open-SCAD for more than just 3D Printing as Open-SCAD is also a very powerful 2 & 2.5D development program also, so we will show you how to use it for Laser Cutting (a gasket int his case) as well as CNC Machining a flange.
