I printed and cured the REV25 parts. Then, I cut threads into the M4 and M3 holes with a standard tapping tool. The trickiest part was keeping the tap aligned while cutting the brittle plastic, so I removed the T-handle and spun it with my fingers, which worked smoothly. I would have printed a spare shell bottom if I knew how finicky it was.
The assembly did not go as planned. I had to add a black nylon nut to the M4 machine screw in the bottom, or it stuck into the shell too far. That elevation interfered with the M3 threaded rod next to it. Even though the pieces sticking out the bottom did not sit as expected, they aligned internally the way I wanted. The M3 rod entered the spinner interior, and the M4 held the axle securely.
