The Smithsonian Institution's Air & Space Museum has a tactile model of the Lunar Lander (LEM) on display in Washington DC. This model is the perfect size for a playmobil astronaut to grab the handrails.

Smithsonian provides the STL to print your own. I figured out what size to scale it up to to fit playmobil figurines, as well as bisected the STLs into halves so they would fit on my printer. Detailed instructions are included on which files to print (I included edited and the original files, as well as a test ramp with handrails) how to assemble and paint the model. Review the directions before printing.

These files were provided by the Smithsonian for educational and promotional use. They may not be sold, or used commercially.
