This is my third copy of Canada's sounding rocket in papercraft format with a fin pattern for balsa wood fins for faster assembly and durability over the faceted supersonic cross-section fins. Also shown is the thin-wall BT-50 stuffer tube which comes in 34" lengths. This one has been test-fitted and marked for cutting. Then if will be permanently fixed to the interior of the airframe. This will minimize contact of hot ejection gas with the model and avoid burst seams
The printer made the best model parts yet. Printed on 110-lb card stock paper.
