Simple Circuit Planet Light

Using LED noodles create a light up sign using 3D printing or Laser cutting.

Note: When 3D printing and Laser cutting this design the size of the stl and svg were increased to 115% of the size designed in this Instructable to allow easier routing of LED noodles.

1. Set workspace to your desired size
2. Add a Cylinder and adjust the size (make sure all dimensions are large enough to have space for the LED noodles)
3. Scroll down in basic shapes and add a Tube
4. Adjust the size of your tube to the "ring" size you want around your planet
5. Change the dimension of the ring to be shorter until one axis is about half the length of the other

1. Select just the Tube shape
2. Find the rotate arrows that will spin it on the workspace floor
3. Adjust position and size until your Tube shape looks like the "ring" style you want
4. Reduce the Cylinder height so that it matches the Tube height
5. Select the Tube shape that is your "ring" and create a copy

1. Change your copy to a hole shape
2. Reduce the wall thickness to create a smaller "ring" that fits inside your original
3. Lower the hole shape at least 2mm (if you do not the LED noodle will sit above your shape)
4. Group your Cylinder and 2 Tubes

1. Scroll down in basic shapes and add a Round Roof
2. Use the rotate tool to move the semi-circle part of the shape to face the ground
3. Adjust the size of the Round Roof so that it covers the carved section of the upper "ring"
4. Reduce the height of the Round Roof until it is even with the rest, it will look patchy when it is even
5. Check and fix any unwanted overlap
6. Group shapes

1. Add a hole shaped Cylinder
2. Reduce size to fit you LED noodle (make sure to measure widest part)
3. Increase height of your Cylinder hole so it goes through your shape
4. Copy Cylinder. hole and place at other entry/exit point for LED
5. Group all shapes and export as stl file for 3D printing

1. Thread one of your LED noodle through one hole
2. Pull LED noodle about 2/3 of the way through
3. Place LED noodle in the cutout gap created in your design
4. Add light tension to LED noodle to keep it in place in round/wider spaces
5. Add 3v button cell battery for power

1. Make sure your shape is at 0 height, and export an svg file
2. Select your shape and lower it into the ground until the workspace floor is visible in your carved path
3. Export a second svg file
4. Send to your laser cutter and follow its procedures to cut 1 base and 2 carved out pieces
5. Glue pieces together matching layers
6. Assemble using procedure from step 6

You can use markers, or paints to add decorations or logo. A battery holder and wire connector can make everything more tidy.
