Draft plastic gearbox assembly

Now with the post machining operations complete (disassembly, stator, rotor, internal gear), I used all the plastic printed pieces to put together a fit test article.  I wanted to use this to verify that all the pieces would not interfere and would function correctly and had an outside hope that the result would be functional.

You win some, you lose some.  Here, the test article did verify that everything fits together seemingly well enough.  However, the printed plastic deforms enough that the rotor isn’t held away from the stator, so it didn’t make sense to try powering it up.

Here’s a video of spinning the planetary gear assembly:

And a few pictures of the assembled unit:
