It is unlikely that this print will ever be needed by anyone else (but you never know). Mostly I am posting this here as an example which may be instructive to people who need to make an odd shaped part.
As the photos show, this part is used to cover the electrical power terminals on an electric motor. The motor in question is an antique Westinghouse CAH 1/4HP motor; the original cover was probably stamped sheet metal. When I purchased the motor it was working, but was in need of clean-up and rewiring. Since the original terminal cover was long gone, I decided to 3D print a replacement.
The photos include a photo I found online showing an original terminal cover (with white power cord), my restored motor, and a "skeleton" print I made as part of the design process to test the part fit.
Anyone interested in more details of the motor rebuild and more details on the 3D printed part design process can look here :

Print in PETG using the provided 3mf file; otherwise :
- Supports on build plate only (0.2 detachable)
- Perimeters = 8
- Infill 100% rectilinear
I used 0.15mm layer height for a smooth look, but 0.2mm or even 0.3mm would probably be just fine.
