+== Pixel-screw.scad ==
+
+This can generate four parts. Set each of the following to 1 in turn:
+
+render_screw = 1;
+render_pipe_screw = 0;
+render_guide = 0;
+render_motor_mount = 0;
+
+Note that they can be combined to see how the model fits together.
+
+The screw should be printed in a one colour (I chose yellow) and the pipe screw
+and the guide should be printed in a contrasting colour (I chose black).
+
+The colour of the motor mount and the other components isn't visible from the
+front, and so only matters to the aesthetics from the back. (I chose blue)
+
+== nail-test.scad ==
+
+Set the following to 0 and to 1 to generate the two halves of this part.
+
+nail = 0;
+
+The difference is that one has a narrower diameter in the holes, so that a nail
+can be banged into each hole. I used 40x1.6mm steel panel pins.
+
+== horn-holder.scad ==
+
+This fits the straight arm from a Tower Pro SG90 servo.
+
+
+== Notes ==
+
+The mechanism for attaching the nail system to the rest of the parts is
+considerably weaker than the rest of the system, and is prone to breakage.
+This really needs redesigning. A square hole/insert would probably make
+more sense here.
