3D model description

My son recently threw away some crafting tubes, which I rescued and made rockets from. I later discovered those tubes were a non-standard size (or at least a size I couldn't find on Amazon), so I changed my design to use crafting tubes more easily found.

For tubes just search for "Craft Tubes" on Amazon. The ones I used are here...
(https://www.amazon.com/gp/product/B07CBRLQKS/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1) Any tube with identical diameter and thickness should work.

These rockets are designed to use the Estes "standard" motor size (18mm: A to C). But only in B or C sizes. I flew them on A8-3s and they only went around 100 feet or so and were almost on the ground before the ejection charge went off. They fly perfectly on B6-4's or C6-3's. At least the "Baby Shark" and "Turbo Jet" rockets do. The bomb rocket we didn't have a successful stable launch on and the Stellar Explorer broke when testing with A8-3s. There were originally parts for 13mm motors and couplers but I removed those parts as they will NOT fly with them.

WARNING: It is up to you to make sure the rocket is stable. Do the "Swing test" which can be found on Youtube. You may need to add weight to the nose cones. Printing them with thicker infill may be preferable to adding weight.

You'll have to figure out your own shock cord mounts and recovery systems. The 18 mm variant's include a half ring on the motor can to tie a shock cord to.

As an extra, I threw in a "Baby Shark Body" that you can put the baby shark nose cone (or any of the other ones for that matter) into, to make a baby shark.

I'll post photos when we have some completed rockets.
