Mercury Redstone for single color printers

My take on the Mercury Redstone rocket. Note: this page only has files for the launch vehicle itself, the capsule and launch escape system for this model are located here:

This rocket was modelled completely from what little historical and technical documents I could find. I tried very hard to make it accurate and to scale. Printed at the scale I have uploaded, the finished project comes out to about 20.5 inches with the main body of the rocket being 1.4 inches in diameter.

The files are split into 4 sections. The capsule and LES once again found here (remixed from the model by @Lopatka_921), the aft section, the center section, and the tail unit.

The aft section includes the adapter, where the capsule meets the rocket, and a checkerboard-looking section. Many of the pieces on this model are located to each other with a "+" shaped hole and a matching connector piece. These connectors can't be seen after assembly therefore can be printed in any color.

The adapter has one red and one black piece. They can both be printed on their flat faces and the three lobes on the black piece will fit into the three cutouts on the red piece. The capsule will then fit inside the ridge of the red piece. These can all be glued together.

The "checkerboard" section is made up of interlocking black and white parts. The thin white pieces are the same part, but there is a top and a bottom for the thin black pieces. The piece that has the circle all along the bottom will be on the bottom. I printed all of these parts on their flat sides. Glue these three separate cylinders together, taking care to make sure the "+" holes line up together. They can then be glued together with two connector pieces, each cylinder having the white piece on top, then glued to the adapter with another connector piece.

The top and bottom center section can be glued on either side of the center stripe using 2 connector pieces. I printed the center sections upright with supports for the letter cavities. Supports may not be necessary if overhangs are dialed in. The red letters can be glued into their holes. The text has a flat side and a side that matches the curvature of the rocket. I printed the text with the flat side down and a brim for ease of printing, but a different orientation for the letters can be experimented with to reduce layer line visibility. This assembly can be glued to the aft section with a connector piece.

The tail section is split into quarters. Two quarters are "solid" and two quarters are split horizontally. The top of each quarter has a square hole that the tail connector pieces fit into. 

The split tail pieces additionally each have a curved slot and a curved split tail connector piece. I printed all tail pieces upside down with tree supports to support the parts that jut underneath the rocket.

My recommended assembly steps are to start by gluing the split tails into their finished quarters with the two split tail connector pieces. I made sure to hold the flat faces against flat horizontal and vertical surfaces to ensure they remain coplanar while glue sets up. Once you have the four quarters, you can glue into halves, then into the whole using the four tail connector pieces while taking care to ensure the top remains flat and everything lines up. 

I used this diagram to get the pattern right:

The post sticking up from the engine can now be glued into the hole left inside the cavity in the tail section. The four white fins can also be glued into their slots. The tail unit assembly can now be glued to the center section with the tail unit top between them and a connector piece.

You should now have a finished rocket! Please leave feedback!
