Omnicron-E 2-stage 24mm model rocket

In my ongoing series of model rockets made at least partially from Pringles cans, I present the Omnicron-E. This rocket flies on two 24mm model rocket motors in the combination you choose. You can fly on two Ds, two Es, or 1 D and 1 E.

To build this you will need:
* A Pringles can (mine was 12.4mm long, so a small snack sized one, but you can make it longer)
* 2 24mm motor tubes (BT-50 size) cut to 95mm each
* A 42mm (BT-60 size) body tube cut to 89mm for the booster section
* Shock cord (I use kevlar line)
* A 24inch Parachute.

The parts begin with a "B" for the booster and an "S" for the sustainer. The sustainer fins can be printed supported (recommended) or if you really trust your printer, use the unsupported version.

The booster fins are designed to go through slots in the BT60 tube. A guide is provided to cut those slots. The root of the booster fins glue to the motor tube inside. The bottom of the booster motor mount (B-MMbase) should be flush with the bottom
