So I had this bag of mini parts ...

And some BT20 scraps. I thought about making an 18mm something, but changed my mind cause it was all too little for that kind of power.
Decided I needed a retro space age rocket, even if it's just a little one.

Found a piece of BT-5 just big enough for a motor. Bent some wiper blade for a hook. 3D printed a couple of rings. Made a mini mount. Used a bit of epoxy on that cause it's plastic.

 

[Alan R]

Why retro space age rocket? Just look at those fins! What else ya gonna do with those???

 

[Alan R]

The real problem of course is what to do with all those little tubes. I played around with those. Maybe some pods? Maybe some outboard?
Finally decided to split my BT-20's with mini tubes.
And a little 3D printing to hold it all together:

Very cool. Look forward to seeing the completed rocket.

 

[Alan R]

Would a ring be too much? Or struts? or Ring AND struts???
I may have to sleep on this one.

Is that a Yankee nose cone?

First, COOL rocket.

Second, I would LOVE to have a couple of those plastic adapter parts for a modified MIRV rocket.
Do you think the plastic would hold up to a 24 MM D12-0 motor blow through (zero delay motors don't have an ejection charge, so while pretty darn hot it's technically not an ejection charge.)

How much would you ask for production and shipping to Washington State?

 

[Alan R]

I think a ring and some struts will do it. I even had a ring already cut to size. whoo hoo. Use up all those random parts.
I'll grab the big bag o' balsa and make some struts

You should go ask over on the 3D print forum. I'm sure someone could do that for you. Ideally you'd want that in ABS (which I can't do) or PETG plastic.

boy, I AM out of date. we have a 3D print forum?

LOL.

Pre-painted most of the pieces in silver. Shock cord mount is a leftover piece of kevlar thread tied through the upper transition.
That other thing at the top of the pic is a 3D printed fin guide.
I'm actually a little hesitant about the next step, but ... time to start gluing.

 

[Alan R]

I was really trying to make a "floating" ring today... and realized I just don't have the patience to make that work. But I like that ring. It's just going to sit on the fins.
Still cool.
I need to remember to put a launch lug on there somewhere.

 

[Alan R]

A couple minor things left to do. Launch lugs. Attach nose cone.
Fun project for a couple days to dig into the scrap pile and futz around.

Ain't 3d printing awesome ! Need a part, draw it up in the computer, print it out. I needed this at age 10. I'd be richer than Musk, lol.

Looks Awesome. Fine build.
