Rocket

This rocket model has two different bases. 1 base for A, B, or C motors & a second base for D motors. The fit is tight enough to eliminate the need for glue. The honeycomb beneath the engine bay can be easily removed with a small pliers or utility knife. I've only built this model in PLA at 0.25mm & 0.50mm step but ABS should work also.
Please be careful and only launch rockets under adult supervision. Don't shoot your eye out ;).
