3D model description

Minimalistic fin can for BT-20 body. This was a project i tried to make simple/light for a quick and easy yet light rocket. This rocket fits an A/B/C sized motor and has a retainer cap to hold the motor in place. the core of this is 75mm long, so only 5mm longer than the standard A/B/C sized motors which are 70mm long. It then has a neck that sticks up 20mm to slide and attach a BT-20 sized tube to the can. I went with tri-fins, one reason is to keep it light, the other reason so that it can be oriented and printed on medium sized resin printers (specifically my Photon Mono X or 6k etc) These fins extend up along the neck just to have more surface area for stability, the BT-20 tube slides under these and on top of the neck with plenty of space as you can see in the images above.

I did not include the nose cone as i used one i had printed a while back but if anyone would like that, i can add that, just let me know.
