Parts 241 through 245 form the descent engine bell.

Parts 241a through 241d are the inner surface of the bell and are basic stacked cone shape with part 241a as the inner cap. I used plain paper tabs to help with the alignment.

Parts 242a through 242c are the outer surface of the bell and are basic stacked cone shape with no cap. I used plain paper tabs to help with the alignment. The shading did not turn out so great on my printer. I may decide to paint the outer surface later.

Part 243 and 244 form a basic tube and cap that attach the bell to the rest of the engine. Part 243 is folded in half for two sided printing.

Part 245 is a cone shape that forms the outer surface at the top of the bell.

On the lower portion of the bell, the outer surface circumference is a bit larger than the inner surface circumference. To compensate, I glued 4 layers of paper strips around the lip between the two surfaces. It adds thickness to the lip and makes it look more realistic in my opinion. I used a black sharpie to color the strips to help them to blend in.

Part 245 was designed to have the lip partially folded in which forms a seam on the bell.

Once the bell was assembled, I fitted it into the combustion chamber assembly. It is not glued into place but simply slips on and stays in place by friction.

Part count to date: 474
