Electric motor box

I printed the electric motor housing with PPA CF because I wanted to make sure it would withstand the temperatures on ships and be resistant to atmospheric and UV conditions. The holes for the glands are 16.7mm. The holes on the top are prepared for embedding threads for M4 screws. Supports are optional; I'm learning to print with PPA CF myself. I made five outlines for the walls and filled them with 20%. The grounding hole is through, so it can be shorted to the ground on the motor as needed.
