BT-55 model rocket parts

Some miscellaneous parts for working with BT-55 body tube sized rockets.

The BT-55 file is a body tube itself. I do NOT recommend using this as a body tube without either 1) Lining the inside down by the motor with cardboard or some form of insulation or 2) using a piece of actual cardboard BT-55 down by the motor. When printed with PLA, this body tube will deform from the heat near the motor after one or two launches. It is suitable for a payload tube, or body tube more than 3 or 4 inches
