**I uploaded the wrong version of the body of the case, but it is fixed now. I got tired of feeling how hot and steamy my printrboard was getting under the metal frame of my printrbot simple metal, so I designed a case to hold it outside the printer, and gave it a port for a 40mm cooling fan. It allows for the wires to be tucked neatly away under the printer body while still getting the printrboard out from underneath. There are also zip-tie slots for keeping heat-bed wires, and the USB cable under control. The hexagonal mesh on the fan shroud is 0.2" spacing, so if you want the hexagonal mesh infill pattern on the cover to match, set your infill to hexagonal, and the spacing to 0.2". Simply stick the case wherever you want on your Printrbot using double-sided foam tape! IMPORTANT! The current cover piece is NOT compatible with the stock power plug. I have customized my printrboard with different power connectors. I will work on a cover to accomodate the stock plug.
