There were three Navy generators designed for generation of FS smoke screens from surface vessels, the Mark 1, Mark 2, and Mark 5. The Mark 1 generator was designed for use on destroyers (including the FLETCHER Class) and larger vessels.
The Mark 2 and Mark 5 generators are designed for use on smaller vessels.

Some part cleanup will be necessary. The 3D printing process uses a waxy substance to support certain part features. 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.
During the printing process, liquid resin is cured by ultraviolet light. Microscopic bits of resin may remain uncured. Let your parts sit in direct sunlight for a few hours to fully cure the resin.
Water-based acrylic paints meant for plastics is strongly recommended. Other paints, especially enamels, may not cure on Frosted Detail 3D-printed plastics.
