Original Blueprint and Gallery Views

The Alpha 259BLANK drawing dated March 18, 2024 specifies a 56 x 15.5 x 8.5-inch stepped polyethylene fresh-water tank with approximately 25 US gallons capacity. The low terrace is 5.5 inches high; the middle terrace rises 1.75 inches and the high terrace rises 3 inches above the low level. The width divisions are 6.5 inches, 2.5 inches and 6.5 inches. The angled end narrows to 12.75 inches over a 7-inch run, and the middle terrace transition is shown 12.5 inches from that end.

The four rendered views and native rotatable model reconstruct this individual print. The middle diagonal transition follows the printed plan; natural polyethylene color and surface finish are illustrative because the print does not specify them. No fittings or probe locations were invented. Reference dimensions have a ±1/4-inch tolerance and capacity is approximate. Use the retained original blueprint and exact part identity to verify fitment; this is not measured manufacturing CAD.
