This model will fit Estes class B and C model rocket engines.

• Stop wrapping tape around your model rocket engines for friction fit!
• Don't lose rocket engines during flight, risking a ground fire!

I have printed SO MANY model rockets that rely on friction fit for the engine housing.  This makes the engine difficult to remove from the model and more importantly, can lead to engine ejection from the model during flight!  This model is a reusable container to house the rocket engine.  I designed this so that it can be printed separately and glued into an existing model, or merged in the slicer.

I apologize for the crude modeling.  I don't use a CAD program (yet) and I just built this model in the slicer software….
