I absolutely love this design. I am now printing it in Pink ABS.
Thanks. The one that you printed for me will be getting its first flight test in a week, looking forward to seeing how it performs.I absolutely love this design. I am now printing it in Pink ABS.
A friend of mine has a 3d printer he's not using and is going to let me have it. I like the idea of 3d printing fins because of the precision ...
Exactly. There was practically zero roll during the takeoff.I don't think a lot of people have appreciated that yet. Unless you induce some warp or have a seriously mal-adjusted printer, printed fin alignment will always be 'perfect'. Roll induced by fins should be gone - stresses on the model should be reduced.
Just have to unscrew the "damaged" one and replace it, simple repair.Great flight. Now, you juts need another tube.
My dad owns a graphics shop so he has a bunch of them laying around. I use the 3in tubes with thinner walls. I'll try to figure out an comparable brand.How do you order those tubes?
What color is the exterior?

I used Inventor to 3D model it. The design files are in the Thingiverse download as the native .ipt file.Hi Ben, what CAD software did you use to create this design? Would you be willing to share those files?
It's free for students but really expensive if you're not in school or it's not provided by your work. A free alternative is Fusion 360 which is similar to Inventor.Thanks, I'll have to get Inventor
Could always trace the shape of an image in Inventor to make the nosecone. Saves a lot of work.I was able to get the Inventor Professional 2020 as an engineering student. I am pretty decent at Fusion 360, but had to do some fumbling around to be able to recreate your design and create new designs for smaller fin cans. I'm experimenting now in trying to get the curvature correct for a Von Karman nose cone using MATLAB and export that data into Excel and then import it into AutoCAD to create the curve and then import into Inventor to create the cone. Having a bit of difficulty with the math in MATLAB, but I am getting close.
