V2 of the Rocket Boosters I previously posted and a mix between different booster solutions I've come up with.

Glue Top Clip Booster Side to Nose Cone 18 near the base of the NC before the shoulder starts.

Glue Main Clip Rocket Side to the rocket approximately where the booster will interface.

Some filing on Booster Bot 2.2 will be required to ensure it locks into the lip on Motor Housing 24mm

a #4 screw will be required to hold the 2 booster mount pieces together.

Note when booster ejection charges happen the nose cone on the boosters will eject and unlock the booster mounts allowing boosters to fall away.
