Another big update, this time we are going to be looking at cncing all the internal shroud components.
So, a cnc in simple terms works by taking a drawing and converting it to co-ordinates so that the router can follow the lines drawn. You can set the depth, speed and tool to be used to allow the machine to cut cleanly. Some projects suffer from whats called tear out, where chunks of the material chip off during the cut process. After taking some measurements from the case, I then drew what I needed in my cnc software.
The picture below shows from top left going clockwise, 2x thin strips to cover the existing cable management cut outs, 24 and 8 pin cable combs, the main front plate for 120mm fan mounting, with holes for the radiator tubing, fans and screw holes. The large piece at the bottom is the basement shroud with 8 pin gpu connect pass through, to cover the existing be quiet! modular sections. Finally we have the left hand side of the vertical shroud including 24 pin cable pass through holes.
So now we have the drawing of the parts we need to cut, we can export the “co-ordinates” to a file that the cnc can use.
Now we need some material, Im using 3mm plastic for this so thats something else we need to tell the machine so it knows how deep to cut. We peel off the protective coating and fix the material to our waste board of the cnc.
Next we have the actual cut process, this happens quite quickly so I took photos as and when I could.
Next we have to bevel the edges for the vertial shroud, rather than do this in the cnc software I use a diy router table on my cnc for small jobs like this. Also see I only use 2 tools to cut the whole shroud, a 3.2mm straight cutter and a 90 degree V bit.
Now we have our pieces we can sand the rough edges, wash them and begin assembly. The photos below show my test piece and the final cut with markings for where the 8 pin connector needs to be, as you can see they line up quite well. Masking tape was then used to transfer the positioning of the vertical shroud. Same goes for the 24 pin.
To fit the parts together I use a trick used by picture frame and box makers, masking tape the front of the components, apply the glue and fold together, it works really well and will leave a nice edge hopefully.
Now we wait for the glue to dry so I can paint this and get it fitted ready to complete the build!
Last thing, the cable combs, these turned out really well, for future projects I will play about with designs to really mnake them stand out.
