Contains 6 tub inserts
Oerlikon tubs, also known as "zarebas", are available separately.
This "Best Cost" design has steps that are slightly thicker permitting the design to be printed in more economical materials. A "Best Detail" design, with thinner steps, is available separately.
Recommended for any 1/96 scale US Navy, Royal Navy, Royal Canadian Navy, US Coast Guard and US Merchant Marine World War II- and Korean War-era model ship.
This product is designed for Best Cost using the more economical Strong and Flexible nylon plastics. This material is very durable and completely waterproof, perfect for Radio Control models. When compared to Frosted Detail acrylic plastic version, available separately, sharp edges may appear less defined and more rounded when printed. Being nylon, this version is generally not sandable and fewer types of primer and paint will adhere to it. Customers report that this product will have noticeable striations (print lines) requiring filling with primer to create a smooth surface. Care is recommended in choosing a paint that will adhere to, and fully cure upon, nylon. Google "primer for nylon" and "paint for nylon" to find good options.
Some part cleanup will be necessary. The 3D printing process uses a waxy substance to support certain part features during the printing process. Although the parts are cleaned by Shapeways, some waxy residue may remain. It can be safely removed with water and a mild aqueous detergent like "Simple Green" using an old, soft toothbrush, Q-tips or pipe cleaners. Customers report that "Bestine" and "Goo Gone" also work well.

From Wikipedia: "The Oerlikon 20 mm cannon is a series of autocannons, based on an original German 20 mm Becker design that appeared very early in World War I. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II, and many versions still in use today.
"Just a few weeks before the Fall of France, the Oerlikon factory approved manufacture of their gun in the United Kingdom, under licence. The Royal Navy managed to smuggle out the necessary drawings and documents from Zürich. The production of the first British-made Oerlikon guns started in Ruislip, London, at the end of 1940. The first guns were delivered to the Royal Navy in March or April, 1941.
"The Oerlikon gun was installed aboard United States Navy ships from 1942, replacing the M2 Browning machine gun, which lacked range and firepower. It became famous in the naval anti-aircraft role, providing an effective defense at short ranges (in practice up to 1.5 km) at which heavier guns had difficulty tracking a target. The gun was eventually abandoned as a major anti-air weapon due to its lack of stopping power against heavy aircraft and against Japanese kamikaze attacks during the Pacific War. It was largely superseded by the Bofors 40 mm gun and the 3"/50 Mark 22 gun. It did, however, provide a useful increase in firepower over the .50 cal machine gun when adapted and fitted to some aircraft. However, it had some problems with jamming in the ammunition feed.
"The Royal Canadian Navy popularized the use of the Oerlikon gun as an anti-ship and anti-submarine gun - while it was not effective against the armour of most larger ships, it was used extensively and effectively against U-Boats, and on the decks of larger ships. A handful of corvettes were fitted with the weapon toward the end of the war, but it appeared more commonly on frigates and destroyers at the time."
