Model Rocket for 18mm motor

This is a printable model rocket that accepts 18mm motors and has a large launch lug for 1/4" rods. There is an internal forward motor block. Shock cord anchorage for me is done by passing cord between the rocket body and motor.

Print the nose cone on its side. Body prints upright without supports. I recommend a brim for bed adhesion. I have obtained satisfactory results with .2 layer height and 75mm/s print speed.
