How to use these files

Carbide Create

  1. Download the desired .c2d file and open in Carbide Create.
  2. Customise the panels where desired.
  3. Review the toolpaths and tools to make sure they'll work with your CNC machine. I'm using the Shapeoko 3.
  4. Export the G-code and load into your favourite CAM software. I'm using Universal Gcode Sender.
  5. Cut the panel. I'm using the PreciseBits MN208-1250-019FC, a 3.175 mm, ZrN coated, 2-flute stub end-mill. I've cut more than 30 panels with a single end-mill and it's still going strong. I'm running a Dewalt D26204K at full-speed (~27,000 RPM) with a feed-rate of 1,372 mm / min.


  1. Download the Sketch file and open in your local copy of Sketch.
  2. Customise the panels where desired.
  3. Print with your favourite laser printer. I'm using the Brother HL-1210W mono laser printer.
  4. Use your favourite toner transfer method to transfer the design onto aluminium. I'm using the Lowell LOOL280 A4 Home Laminator, customised to support much thicker sheets of aluminium.


  • These panels were originally printed on 3.18 mm thick aluminium at a size of 45 mm x 223 mm for 1U wide and 90 mm x 223 mm for 2U wide. You should double-check these panels will fit into your rack before printing or cutting.
  • Each Carbide Create toolpath has a different depth of cut. This is to take into account issues with the Shapeoko's belt-driven Z axis.
