This adapter allows you to display your rockets made using ellipticaloptician's Model Rocket Kit (and any derivatives) on any of the many 18mm stands you can find here on thingiverse. Just find and print the 18mm stand of your choice and print this adapter. Put them together and voila! You got a stand that fits your 3D printed rocket.

NOTE: Do NOT use the 18mm adapter rings from the Model Rocket Kit with this adapter. It's designed to go through the fin unit and is flanged on the bottom
