Apollo Mission including the moon, astronaut, lunar lander and moon stand.

Moon: I split into two halves using meshmixer and added a hole/peg. I also have the full moon stl. In order for the peg to fit, you need to scale the moon halves to 225%.

Astronaut: no change from original.

Lunar lander: no change from original. Scale as desired. I scaled to 150%.

Stand: no change from original. Scaling down may be better but I did 100%.

I printed everything on a heavily modified DaVinci Pro 1.0 with 100% fan at .15mm layers. Varied infill and perimeters between everything. I used glow PLA at 210C. Various brims were used as well. Everything can be printed without supports.
