That's ok Mike, we all gotta start somewhere. First question, do you have a 3D printer? Or, are you planning to use one at school or a library or something (where you'll probably be limited to PLA plastic). If you have your own, is it limited to PLA (or PLA types) or can you print in ABS or PETG or something else?

The only reason I could do single-wall (that's just one noodle of extruded plastic, or about 0.5mm thick) is that I was printing in ABS which is much less brittle than PLA. Thin-walled ABS prints become very flexible.

Vase mode, that I mentioned, is a printing method for single wall prints, in which there is no discrete 'step' when transitioning layers as the print progresses upward. The extrusion is a continuous single wrap around the shape you specify.

Do you know how the slicer software prepares your design for printing? In many cases, there is no need to specify wall thickness in your CAD program - you can just do a solid shape, and then specify the wall thickness in the slicer. Do you know what slicer software you'll be using?

Resources, hmmm. For 3D printing in general, or specifically rocketry related? For rocketry, we'd probably need to find some threads on one of the forums.
