Moon Rocket for single extruder printer (adhesive-free assembly)

thingiverse

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. I believe that the cause of that is that with the way the nose cone, central pieces and base fit together there is a fraction of a millimeter of length being added at every joint. These tiny differences stack up to a noticeable gap when the side panels are added. The size of this gap can vary with different prints. 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.
