Rostock 3D-Printer printing model rocket

Here is my Rostock 3D printer printing a model rocket. The Rostock is especially suitable for this task, as it has a very long build volume of up to 40 cm. Most other 3D printers are limited to about 20x20x20cm. This model rocket will be flown on an Aerotech D24T, it weighs about 150gm, i.e. it is a little too heavy for a black powder 18mm motor.
