A model rocket, theoretically suitable for launch. This is sized for use with any standard A, B or C model rocket motor. Due to weight (plastic being heavier than cardboard) I suspect that it will require a higher end C motor to launch satisfactorily.
The .stl files are needed for actual model creation. This was originally made in Autodesk 3DS Max and the .3ds file is included for anyone who wishes to edit it.
This is specifically designed to be printed on a MakerBot or RepRap style printer. The few limited overhangs involved should be well within the abilities for these style printers. The largest pieces are 10cm vertical and only a couple cm across.
The file units used were mm
And a final word of warning: Be at a very safe distance if and when you try and launch this! It's an untested design (even if based off of many generic model rockets) printed on a home printer. You are putting explosives in the tail end. Best of luck and stand clear!
To assemble, you will need to print one each of RocketBase.stl, RocketCone.stl, RocketConePlug.stl and RocketMiddle.stl. You will also need three copies of RocketFin.stl
Depending on the tolerance of your printer you may need a little sandpaper to fit pieces properly. Alternatively, you may wish to use a little tape or other material between parts to increase the snugness of the fit. I have built a fair margin of error into the file. Adventurous souls should be able to adjust their print settings to change how snugly the parts fit together.
Also, you will need to figure out your own method of rocket retrieval. Due to the sturdiness of the materials and relative lightness I suspect you could get away with just letting it fall to earth and have it suffer minimal, if any, damage. A standard parachute system could also be used.
Slid the three RocketFins into the slots on the RocketBase. Depending on tightness of fit you may wish to glue these in place.
Glue RocketMiddle onto Rocketbase.
If you will be using a parachute system run a cord through the hole in the RocketConePlug and knot it off so it can not be pulled back through. This will allow you to secure the cone to the rest of the rocket. Then glue RocketConePlug into place at the bottom of RocketCone.
If you are using a parachute use a little sandpaper to make sure the cone can slide on and off the rest of the rocket freely. If you are not then consider gluing the cone on.
Depending on how you will be launching this, you may wish to glue a small piece of a straw to the outside to act as a launch guide.
Shove a parachute or drag line into the top, a rocket motor in the bottom and launch!
