Are you familiar with RockSim software used for the flight simulation of model rockets? If you are, that software makes it easy to draw model rocket parts and export the files into the 3D printers slicing software https://www.apogeerockets.com/educa...wsletter476.pdf

The article also reviews the workflow for 3D printing and gives tips on where to learn about 3D printing and 3D printers from YouTube channels like "Makers Muse" and "Todays 3D Print".

I is best to first learn how to draw the 3D parts, since free 3D print services are easy to come by at places like local libraries and schools; and there are for pay 3D print services like Shapeways. A good 3 D printer can cost less than $200, but you have to be mechanically inclined and willing to learn and put up with the nuances of the printer you purchase.
