Rocket for single extruder printer. All parts snap together for easy, glue-less assembly. Could be treated as a simple puzzle. Once fully assembled the rocket stands approximately 173.08 mm tall.

May or may not require minor fitting depending how accurate and consistent your print is. Has 0.2 to 0.3mm clearance between parts in most places.

Printing quantities and suggested colors:
A-NoseCone: 1x Red.
B-5Stage: 2x Red, 2x White (top level)
C-4Stage: 2x Red, 2x White
D-3Stage: 2x Red, 2x White
E-2Stage: 2x Red, 2x White
F-1Stage: 2x Red, 2x White (bottom level)
G-Base: 1x Red (requires support enabled)
H-Center: 2x (not visible, color does not matter)
A-NoseConePrintAid (Print this one along with A-NoseCone. This will force your printer to move back and forth between the two parts, giving time for the thinner layers at the tip of the nose cone to cool before another layer is laid on top, giving better results. )

All parts will print best if laid in the upright position on the printer bed.

B to F can be difficult and time consuming to put back in the correct order if they get mixed up. It is recommended to keep them organized until assembly.

This rocket is inspired by a German V2 test rocket.

UPDATE
After noticing that a lot of people like to print this rocket as big as possible I have added STL files for the base with separate dovetailed legs. These files have been named with the "G2" prefix. This should allow people to print even larger rockets. However be advised that the dovetails for the legs have been created with zero clearance. Some fitting will most likely be required for assembly.

UPDATE 2
I have noticed that many prints have a problem with a gap between the nose cone and the side panels below. I believe that the issue comes from some printers losing a fraction of a millimeter in height due to the initial layer being "squished" into the platform to achieve proper adhesion. This difference in height can stack up at every panel to a noticeable gap. This gap will be different for every printer, ranging from nonexistent to very noticeable.

I have printed a 200% scale rocket and have assembled the base, middle pieces and nose cone without putting on the side panels first and measured the vertical space that the center pieces must occupy with a vernier caliper (should be 65mm at 100% size). I have noticed a 0.7% dimension discrepancy in mine so I have resized all my center pieces by stretching them by 0.7% in height in my slicer program. Everything fitted flush with zero gap after that.

For better fit I would recommend measuring your partially completed rocket and adjusting the height of your side panels in consequence just like I did.
