My Biggest Rocket Ever - How I Built It 

Looking forward to a launch video, keep up the good work!

To make the the tip of the nosecone you could have just created a sketch on the front plane, used the "Intersection" tool on the lower part of the cone, then created a tangent curve between the 2 top points of the lower part of the cone, created a line that splits the curve in half, and then used the "Revolve" function on one of the halves, using the line that splits the curve in half as the revolve axis. Also, to make the lower part of the cone you just needed to extrude a circle with the "Draft" option checked.

This it cool stuff. I was surprised you had so few subs, you deserve more. Looking forward to more content.

Cool video, interesting solutions to problems without throwing money at them, good presenting :) Keep making bro i subbed :)

Interesting video; you might wanna use the circular pattern feature for making fins instead of copying and pasting (just model one fin and pattern it around the body tube), and you can try the revolve feature for making the nose (model the side profile of the nose and rotate it 360 degrees)

Let me know if you need any 3d models for printing I make them in a short period of time.

Please check your CG before launching. Fins that big with all that weight at the bottom, could wind up with a bad flight.
