…maybe this looks more believable? …
edit: I should probably go and explain what happens here
@0:00 The Motor Housing Cap sits a 3/8" away from the finger-drive shaft collar and is being pushed against it until form-fit. A spring inside recoils (and that takes a fraction of a second until it releases a pin which previously has locked the Cap’s threat in place… imagine a small rim along the inside of the threat’s ending edge).
@0:01 The Motor Housing Cap springs back until it reaches enough clearance to rotate into either direction (at this point you can decide wether to push it back in or turn it into the arrows direction , as indicated on the cap).
@0:02 the cap is being rotated Clockwise to be released from the Motor Housing and then obviously pulled away.
The caps all sit 3/8" away from the finger drive shaft collar and are not rotatable
