Not hard at all.Fins today. I'll try to construct a nose cone tomorrow. Tricky puzzle. Hopefully it wont be too bad.

Wow. You outdid yourself there. Thank you for your interest and help. Some of that will be useful.Anyhoo, probably more than you wanted to read, hope this helps.
Interesting thread.See post 55
Enemy of good is better, enemy of better is perfect.Interesting thread.
Time to just say it now.. I'm getting really frustrated. The body sides are not equal length and it's giving me lots of headaches with the NC. Inside lengths are 77mm, 70mm, 68mm
Not sure where I'm going: deal with it, re-do the body fold, or just take a long break from frustration.
Last option most likely at this point.
When I started this I honestly thought it would just fold together in a few hours.All three triangles need to have the same length SIDES, they do NOT have to have the same length BASE.
Build the pyramid first, then build a shoulder that fits into the body, THEN figure out how to mate them up.
Lol, it gets easier after your first 100 tries!When I started this I honestly thought it would just fold together in a few hours.
I confess that this project has been one of the longest, most frustrating builds I've ever done.
Thank you for the tip. I can see that you're correct. I think the way to do that is get out the compass again and make a new NC pattern.
Air is still bad outside here today so nice time to tackle the problem.
Just like @BABAR said there.. I used a compass to make equal sides, but different length bases and got a working NC with built in-shoulder. all one piece. Used an estes mount on the nc for the shock line.All three triangles need to have the same length SIDES, they do NOT have to have the same length BASE.
Cool!I had lots of downtime at the last launch so I played with this. Got a nice origami nose cone finally just using cardstock.

I rolled a launch lug from a coffee filter (hey, i was camping.. didnt have lots to work with). First flight, D12-5. it hung on the rod. I cut the lug into 2 short pieces, used some quick epoxy and tried again couple hours later.
Second flight, I decided a bit bigger motor would help also. AT-E20. ... just like a disaster video... off the rod and end over end. Most likely the heavy motor causing a CG error.
No serious damage. It's going to get about an ounce of clay into the nose and that should stabilize things much better.
220 Grams with the D12 motor and streamer.

Say it isn’t so! This is a cool design and should be easily fixable.I've been updating other threads and completely forgot about this one.
3-cubed had three launches
1. spectacular failure ... looks like it got hung on the launch rod,
2. spectacular failure ... AT E20, fixed and separated the lugs, same thing, end over end. Needs more nose wieght
3. spectacular failure ... Estes D12, added an ounce to the nose, end over end again
Yup, @BABAR is right. needs way more plumage. Maybe if those fins were coming out the edges instead of being on the flat it might work.
anyway, done with this one. shelved and relegated to the failed experiment pile. it was just a hack that was fun to try, but not interested in doing any more with it
Ok @BABAR , just for you, because I respect your opinion.Say it isn’t so! This is a cool design and should be easily fixable.
PLEASE don’t shelve this one, there are far too few three sided rockets out there.
HA. love it.Maybe put on a Toblerone wrap.
I can see from the pic that's exactly the orientation I'm thinking of. align the edge with the opposite side.see video to get the orientation I am thinking.
i see what you did thereThat’s gonna look great from every angle!
Yay!Now with more fin. Finally got a good flight, but the streamer didn't pop out. It gets hung up inside there.
very little damage, cause, hey it's cardboard. and it flies now.
