3D benchy bookmark

Insert a pause in the print after the supports have been printed and color on them with a sharpie, so that the supports don't stick to the model but still hold up the bookmark; this technique only works on the flat bookmark part and not on the benchy, because the flat supports will all be finished in the same layer.
