Case for ramps with 92mm fan and for diamond hotend

This things is a case for ramps 1.4 and specially for Itopie or Prussa, you can put a stepper expender if you have a Diamond Hotend.
And have a place to add a converter 12V to 5V ( Step Down Converter Module LM2596 ) better performance than the converter of the arduino card.
The case have a Computer fan of diameter 92mmx92mmm for best cooling.
Fixe this to your printer with screw for wood.
You can modify this case if you need, i have upload the solidworks files.
I hope you enjoy :-)
