Remote Spool Tweaks

For the Inner Rings x2: Slightly moved the inner ring tabs to make insertion and alignment easier. Each one fits a specific wall piece.
 

For Electronics: Added channels, enlarged board container slightly, added helpful Xs.

If you downloaded before August 3rd, download the rings again! I mixed them up with an old model, and they won't fit correctly. It has been fixed.

1. Moved the inner ring tabs a few degrees to make it easier to align.
   Note that each ring fits a specific wall, so test fit before screwing down!!
2. Enlarged the board container slightly, Added Xs for my own sanity of where not to put the motors, and added a channel for cables which may defeat the purpose, but I want to be able to get the wires out without breaking it!
