This is a project that generates complete model rockets designed to get you up and flying faster and cheaper than purchasing kits.  All necessary parts (other than parachutes) can be generated, including but not limited to:
 

- Tube-sizing gauges for perfect fits, and test parts to confirm

- Nosecones

- - Eleven different nosecone profile types

- - Threaded nosecone plugs/caps, for payload or weight adjustment

- - Hollow or capped, with cord mount options

- Transitions

- - Threaded plugs and caps options

- - Cord mounts

- Tube Couplers

- Rail Guides

- Launch Lugs

- Ejection Baffles

- - Half-moon, or holes styles available

- Fin Cans

- - Completely customizable profiles

- - Supports scaling, skewing

- - Arbitrary canting available

- - "Polygram" style options (e.g. the Chicago Star shape)

- - Airfoiled fin options

- - Fin rings

- - Fin nacells

- - Tube fins
- - Fillets (downloaded version only)

- Centering Rings

- Engine Blocks

- Clustering

- Threaded retainers

- - Three styles

- - Threaded cluster retention available (mason-jar style plate)

- Staging Adapters

- Tube Cutters (downloaded version only)

- - Takes standard construction blade

- - Includes guide sleeve

If a generated part doesn't make sense, it's probably meant to generate in vase mode (and there are many vase options present)

When in doubt, refer to the examples in the zip file.  I know that probably doesn't help when using the web customizer, but if you play along at home (using OpenSCAD), the examples can be  useful. 

Models included with this project are not generated by it, but necessary for the parametric tube cutter imports and fin fillets.  Make sure they are in the same directory as the .scad file of this project.  The web customizer does not support these features; they are available in the downloaded version only.

While main body tubes can be 3D printed when using enough thickness (to resist thermal meltdown), it is recommended to start with your own secondhand tubes (paper towel tubes, wrapping paper tubes, ULINE, you name it) as a good way to save time and money.

I apologize for the lack of detailed documentation.  This project assumes you are familiar with not only model rocket components, but also have a good understanding of your slicer, i.e. if you can properly slice a 3DLabPrint airplane, you will not have too much trouble here.

That being said, I will attempt to address questions in the comments as time allows.
