 Greg <unk> had already been working on a new model of the USS <unk> for the " Flashback " episode of Voyager when he saw the test footage for " Trials and Tribble @-@ ations " . He promised to make a new model of the Enterprise too , but warned that he didn 't know when he would have time to do it . He actually started work on it immediately , and together with his colleagues he not only built a 5 @.@ 5 feet ( 1 @.@ 7 m ) long model of the Enterprise , but created a new model of Deep Space Station K7 and the Klingon cruiser as well . The Enterprise model was the first to be built of the original Star Trek starship in more than 30 years . Other props were also recreated , with around 1 @,@ 400 tribbles created for the various scenes . They were purchased from Lincoln Enterprises , a company set up by Majel Barrett , widow of Star Trek creator Gene Roddenberry . The rest of the era @-@ specific props were newly created , and were made by Steve <unk> .
