Please visit http://OpenSCAD.DIY3DTech.com for more information on this and many other projects! As in this episode we will be finialy building that that 40mm to 500mm fan adapter for the extruder of the Wanhao as I simply stuck the Allen wrench in there just one to many time plus it needs more air dosen’t it? As you you never can enough cool air right! But in all seriousines this model shows how build up simple manifolds in Open SCAD which is a handy ability for have.
