Case Ordering Instructions:

Any Material Can be used for the case however I recommend 9600 Resin with Spray Painted Surface finish. That is proven good. JLC will probably complain about wall thicknesses, tell them that you accept it as is. Clear is cool however the material does not have great dimensional stability so warping with clear is possible, YMMV. Make sure you select "Plastic Enclosure" as the application
