Rocket ejection plug (for Estes)

This is a plug (ejection plug) for parachute.
- O.D. 25mm (simple and older one)
- O.D. 23mm (newer version, bevels on edges)

When I started rocket hobby with Estes models, I had problems that my parachute was sometimes burned from ejection discharge. This plug is inserted after rocket motor and it is protecting parachute from burning.
I recommend make it thin, light and make it from PLA ! usually you lost this plug and save the nature by using compostable plastics!
