Model Rocket Nosecone and Tailfin Section for 30mm (or 1.25") Cardboard Tubes. 29mm motor.

Description

I Designed These Pieces To Turn A 30Mm Cardboard Tube I Had Laying Around Into A True Model Rocket That Accepts 29Mm Motors. This Works Perfectly With The Cardboard Tubes From A Reynolds Wrap Aluminum Foil Roll. I First Fiberglassed The Cardboard Tube With 1 Layer Of Fiberglass And Epoxy, To Make It Stronger. Fiberglassing Wasn'T A Necessary Step, But Will Produce A Stronger Rocket. This Also Made The Tube Slightly Wider But That Difference Is So Small It Should Not Matter. I Slightly Undersized The Od Of The Parts So It Will Work With Either Fiberglassed Or Non-Fiberglassed Tubes. My Tube Measured Approx 28.6Mm Inner Diameter. I Highly Recommend Using A Raft For Both Prints. Both Objects Should Be Printed Upright With A Raft. This Means The Nosecone Should Be Printed Pointing Up With A Raft Under Its Bottom. The Tailfin Should Also Be Printed Upright With A Raft To Minimize Lifting. Even With The Raft I Still Unfortunately Experienced Some Lift, But It Was Not Enough To Mess Up The Print. Once Finsihed, Just Remove The Rafts, And Slide Into The Tube. It Should Be A Tight Fit, With A Small Amount Of Resistance. The Tailfin Should Be Epoxied In Place. The Nosecone Should Be Attached Using A Shock Cord.
