The LEGO Factory theme, active from 2005 to 2008, included the Space subtheme, which featured fan-designed sets. Two notable sets from this subtheme are 10191 Star Justice and 10192 Space Skulls, both released in 2008. The 10191 Star Justice set, designed by LEGO fan Chris Giddens, contains 895 pieces and includes a spaceship, a command center, and various smaller vehicles, all in a blue and white color scheme with six minifigures. The 10192 Space Skulls set, designed by Mark Sandlin, consists of 956 pieces and features a skull-themed spaceship and vehicles in black and red, accompanied by five minifigures. These sets were part of the LEGO Factory's initiative to promote creativity and fan involvement in set design.
The Factory theme was introduced in 2005 and was powered by LEGO Digital Designer (LDD), a free LEGO virtual building program for the computer. Using the LDD people could design their own 3-D LEGO virtual model, and submit it for purchase using the LEGO Shop-at-home. The Factory platform was also designed to allow users to view and purchase other users custom creations. Once ordered, these Factory sets came in special packaging that showed the model as well as all included LEGO elements needed to build the design.
During Factory's beta phase, The LEGO Group sponsored a contest where people could submit their designs, in which 8,000 designs were submitted and people and LEGO Master Model Builders voted on the top models. Ten models were selected to become real LEGO sets available exclusively through LEGO Shop-at-Home.
In 2009, LEGO Factory was replaced by Design byME.
