Rocket Parts for Estes engine rocket

We built a model rocket from a discarded cellophane cardboard tube. The motor holder adapted the Estes C and B engines to fit our tube and the spacer and end cap hold them in place. We added 3 fins and used the alignment tool to keep them square while the glue set. Everything except the end cap was glued in place with super glue. We had a nose cone that fit, so I haven't designed one.
