This 3D-printed model of a space shuttle took five years and about $30,000 of materials to bring it to life in a Heathmont front yard.

How it happened: Friends Adam Wieja and Peter Sawyer have been creating models since 2011, but have been spending about 10 hours most days on the rocket, as well as the 3D printer working overnight.

The display includes plenty of moving parts, three fog machines and about 40 miniature astronauts and crew members to simulate liftoff.

What they said: At 76 years of age, Wieja said what began as a hobby had become a passion.

“Astronomy fascinates me a lot,” he told the Eastern Melburnian. “I don't want to waste my time in front of a TV – to be like a couch potato. I will continue as long as I can.”

The back story: Wieja was born in Poland and ran away from home as a child, travelling through Austria, Germany, Belgium, France and eventually Australia.

Working in many jobs over the years, including in car manufacturing and as a stockman, he settled down and retired in Heathmont about 14 years ago.
