Introduction: 3d Printed Model Rockets & Stand

In this instructable we'll be creating a 3d printed model rocket launching stand, and a 3d printed model rocket. I've made this instructable as simple as I can and it will focus on assembling the 3d printed parts and not on how to create them. 

I hope that you enjoy this pastime has much as I do, and with 3d printing it's easier than ever to do so.

Step 1: Constructing the Launchpad

There are three files that construct the model rocket stand. 

They are the "ModelRocketBaseStandOverlatch", the "ModelRocketBaseStandUnderlatch", and the "ModelRocketBaseLauncherPad".

The two files that make up the launcher stand, "ModelRocketBaseStandOverlatch", "ModelRocketBaseStandUnderlatch", need to be printed twice so that there's four in total. 

The "ModelRocketBaseLauncherPad", is the bast deflector that the rocket will rest on. It's design so the guiding rod can be inserted either in the center or on one of the sides, so that the rocket itself launches from the center. 

Step 2: Printing the Guiding Rod (Optional)

You can go out and buy a metal rod with a diameter of 3.5mm to launch you printer rockets from your printed stand. Or you can save gas, time and money by printing out one. I've designed and attached one that can be easily printed and constructed to the desired height. One side is slightly flattened so it prints better.

The file has one section of rod that's 20cm in length and has a male and female side so as to allow for connection of the printed rods to one another. 3 printed sections should be enough.

Step 3: Rockets (Motor Housing)

This particular motor housing is designed to hold a C6-5 ESTES motor.

Other size motors could easily be modeled for if the specifications are known.

The housing has four grooves that accept stabilizers and other modular attachments, which I will elaborate more on in the next step.

An engine cap needs to be printed as well so as to keep the rocket engine in the tube.

Step 4: Rockets (Stabilizing Fins)

I've created five variations of stabilizing fins for you to choose from.

They're shown in order from the first variation on the left and the fifth variation on the right.

You can mix and match the fin styles, print only two or print all four for your rocket, the choice is yours.

Step 5: Rockets (Nosecone)

Three different styles of nosecones to choose from.

Each snaps on to the motor housing, and each has a hole at the tip to allow for the pressure of the back-blast to escape. 

Step 6: Igniter Plugs

Though igniter plugs come packaged with the motors, I thought it best if you had the option of printing out your own.

You will also need a method of ignition in order to make your rockets to go boom.
It would be possible to make your own with a little ingenuity, wire and a power source, but I'd suggest buying a launch system.

Estes make an Electron Beam Launch Controller that I've been using for years, and I haven't had any problems with it.

Step 7: Parting Words

For those who've taken the time, and plastic, to print this out and use it, I hope that you enjoy it.
If there's any problem with the design of the rocket parts or the stand please let me know and I'll correct the problem.
Also if you have any designs that you'd like to see made let me know and I'll do my best to create them.
