CR-200B cooling modification

The CR-200B is a very nice enclosed 3D printer, but I expected less noise. For the modification I used 2x 50mm and 1x 120mm PC fan. The 50mm fans blow towards the driver board, while the 120mm fan blows the hot air to the outside. You only need to drill the holes for the fans and 2 holes for mounting it to the printer (use the original holes). For the power supply I made my own 24V to 12V power supply converter, but you can also buy it on the internet. Good luck.
