Odd'l Rockets Cutaway Engine Build, Part 4, Gluing It Together

Test fit the end caps without glue to get an idea how they fit the curved ends.
Spread a thin coat of wood glue around the tube end and slide the end cap from the inside towards the outside edge.

Press the folded triangles into the glue with a tapered burnisher like this pen tip. The ink tip is retracted, I'm using just the plastic end.

There is a white glue coat on the end flap piece.

Press the ends of the long engine print into the end cap glue flap.






Turn over the half tube. The long side flaps should be opened out.
Apply a line of glue stick down the flap.
Burnish the long glued side flaps onto the tube edges.

Here's how the nozzle end will look.
If you don't get it right, chalk it up to practice. You can always print another and try again.
