This in another motor cover that I have modeled and will use on my cnc milling machine. It is not finished, the one I printed needed a lot of filing to get the XLR connector to fit properly and the unsupported overhang is a pain to print correctly. I will remodel this to fix these problems and post a finished part as soon as I do. Please do not waste filament if you want it perfect. I modeled it with the XLR connector in mind and on my application it is oriented downward toward my controller box built into my machine stand. You will need to purchase 4 4mm x 30mm pan head screws and install it the same way as my other covers for the Nema 23.
