CAD/3D rendering of custom packaging insert

We have two custom boxes, both with the interior specs of 9.5 inches wide, 7.5 inches tall and 2.5 inches deep for which we need custom inserts rendered. The first box contains: - a notebook - 8.375 inches tall, 5.5 inches wide, and 0.5 inches deep - a pen - 6 inches tall, 0.5 inches wide, and 0.5 inches deep The second box contains: - a hot sauce bottle - 7 inches tall, 1.75 inches wide, 1.75 inches deep - a lip balm - 2.75 inches tall, 0.625 inches wide, 0.625 inches deep - a pen - 6 inches tall, 0.5 inches wide, 0.5 inches deep - a folded 5x7 line sheet - 3.5 inches tall, 5 inches wide, <0.25 inches deep folded Our sketches show the layout we would like for each (please see attached). Ideally, we would like the height of the insert overall to come within an inch of the box height (so more like 1.5 inches), and to conform with typical production specs of 0.25 inches minimum of wall. We need a 3D rendering that is to-spec to send to vendors for accurate quoting. Measurements should be placed on the drawings.
