LEGO Ideas 21321 International Space Station

LEGO Ideas 21321 International Space Station set by German Fan Designer Christoph Ruge is a 864-piece set released in 2020. The set was part of the Extraordinary 10 Year Anniversary Fan Vote held in June 2019, which was part of the LEGO celebration to highlight 10 years of collaborating with LEGO fans through LEGO Ideas (called LEGO CUUSOO up until 2014). To make Christoph's Idea set a reality in official LEGO form, LEGO Designer Samuel Johnson and Corvin Stichert collaborated with Graphic Designer Crystal Marie Fontan.

It was retired in November 2022 with a lifespan of 33 months.
