54MM rocket motor simulator plug

Keeping with the theme from my 75mm motor simulator, the need for a 54mm version came up. An NASA SLI team needed a plug for deployment charge testing prior to the installation of their motor retainer. Two of these were printed for installation in the fore and aft end of the motor mount tube with an all thread and nuts used to keep them in place.

This model is based on Aerotech's motor and aft closure published dimensions. The model has a 1/4" hole in the middle for additional utility.
