This heavy transport is a favorite of smugglers due to its speed and capacity.  The Koralien system planets are best known for their space-shipyards and smugglers, which works out well for the Renegade Alliance whom they have sided with against the oppressive Scythe Empire that wanted to acquire their shipyards and stop their smuggling.  Model is about  18mmL x 11mmW x 4mm H (~11/16"L x 7/16"W x 3/16"H) designed by Tom Utar, sold unpainted, and my 1/2" diameter Versi-Base(tm) is included.
