Please visit http://OpenSCAD.DIY3DTech.com for more information on this and many other projects! As in this episode we will be looking at new water-bath which I designed in Open SCAD for a small CNC machine (a 3040 in this case) to cut and engrave various objects that either require cooling or suppression of particulate such as carbon fiber during the cutting process for safety.
Also if you looking for the mini-vice I used in this build, you can order it here: https://goo.gl/kw9oaH
You can also see other videos of this in use here:
