This is my 1:185 scale Apollo 11 Saturn V cutaway!

One half preserves the original rocket's exterior, while the other reveals its engines, propellant tanks, and internal structures.

I modeled it in Fusion 360 and 3D printed it in 23 pieces. Some internal details were simplified or reinforced to make them printable.

Really happy with how the finished model turned out!

The owner of a SIG AR in .223 accidentally loaded a .300 Blackout round. The bolt was stuck so bad, that we were unable to move it. So we had a local business water jet it in half. (more like a 1/3).
