Make Your Night Light Rocket for Kids DIY

Does your kids love Space, Rockets and 3D printing? Then this tutorial how to make Night Light for kids DIY project is for you! Our Rocket Night Light is super easy to make. What we need for that? Almost nothing. We built a Rocket Night Light using seven grommets, eleven LEDs, can from beer (I think Dads will appreciate this part of project), and 3D printer.

What we like most of all in this project - it is our Rocket Night light doesn't require soldering at all!

Most time consuming part is 3D printing. To print seven parts of Rocket Night Light it takes about 7 hours. The rest is quite fast and easy. It takes about 15 minutes. Dads can make this project together with kids. You can have fun together. I would not allow children to cut foil, it can be a bit dangerous. The rest of project is absolutely safe and easy.

All STL files can be downloaded from our website: Catsonamission.com

Supplies

7 grommets d2.5mm l=10mm
11 leds d=4.8mm of any color you like (we use blue)
1 can from beer (any brand you like)
about 45 ramm of Filament for 3d printing (we used CoPET. Its is easy printable, strong and flexible enough)
2 battaries AAA
1 piece of sand paper

Step 1: Let:s Collect All We Need

Step 2: Step 1: Print Templates for Cutting the Aluminum Foil

Lets print templates first. Then we will start printing the rest parts. And we will have time for scratching and cutting.
We need to print two templates: face_rocket_template.stl and back_rocket_template.stl

Step 3: Prepare Aluminum Foil From a Can

Cut the foil plate from can. Make it flat as possible. You can use usual home scissors also.

!!!IMPORTANT!!! Scratch the foil with sandpaper. The foil is initially covered with a protective film. So we need to scratch it to have electric contact. One side is enough.

Step 4: Cut "aluminum Wires" From Aluminum Foil

Draw the wires with felt-tip pen.
Then cut with scissors. Make contour of cutting a bit bigger. Late we will correct that.

Step 5: Print the Rest of the Rocket Night Light Parts

Download full Archive of STLs here. I used 0.2mm layer height and fill density 40%. It allows to save time. But you can experiment with that.

Printing doesn't need supports. I like that.

Step 6: Mount Our "custom Wires" and LEDs

Lets mount our custom wires on to "rocket-middle" part.
!!!IMPORTANT!!! It's important to avoid short soaking. Browse all tracks and cut it a bit if it is needed. Mount and check both sides.
!!!IMPORTANT!!! Its important to observe polarity. Place all LEDs with long leg to bottom. Otherwise it will not light.

Step 7: Lets Mount Batteries - Night Light Almost Ready!

Step 8: Check

We need to check 3 things: not having short circuit (if you have it - your batteries will heat fast). Check for good electric contact with LEDs. Use tweezers instead of switch (on this step) to check that LEDs are lighting.

Step 9: Mount a Switch

At first lets check. Did we placed a foil piece into upper part of switch? It's quite important. Otherwise the switch will not work.
Put upper part of switch and fasten with a grommet

Hope your kids will enjoy it. Rocket Night light for kids seems to work!
