Step 1: Designs
I went through a couple of designs. It was difficult to to get the "D" and the globe to fit together like I wanted them too.
The problem comes from trying to simulate the Discover logo as close as possible. You will notice there is a small white halo around the globe. This suspend the globe in the Design. Not every two dimensional logo translate to 3D design.
Step 2: Redesign
The Discover Channel/Discover Education logo is a simple but really cool print.
Initially I was going to use a basic sphere for the globe. From there has I was painting my prototype, I decided that a texture globe could take this to another level.
I found a stl file through www.thingiverse.comand and merged the "D" and the globe together in 123D Design.
*note the a textured globe is a very complicated and large file, give it time*
Step 3: Final Design
With a texture globe I was able to use the texture has a way to set the sphere into place with the "D".
This took a little work.
On 123D Design with you subtract one shape from another you lose one of the shapes.
1. On the same design grid I put the globe intersecting with the D.
2. Then I trimmed the bottom of the globe so the globe has a flat bottom so that it will rest. One of the adjustments I had to make when I went from 2D to 3D on the logo.
3. After I created a flat spot on the bottom. I copied and pasted the globe giving me 2 flat bottom globes.
4. I subtracted the globe from the D.
Step 4: Export for Printing
Since I was printing in two different colors I need to separate the two solids, and export them to print individually.
I also wanted to print the "D" flat so I had to rotate it 90 degrees.
I exported each solid. From there I wanted to max print for my printer size. I scaled each solid up by the same factor.
*the texture globe is complicated file it takes time time to export*
Step 5: Paint
I tried several shades of blue before I settle on one that I liked best.
The "D" is printed in a shiny black filament, so I wanted to complete it with the globe. I choose to use a translucent blue as I thought it worked nicely with the black.
Using a basic green and gold paint marker, I painted the land masses and changes in elevation.
Step 6: Lighting
I wanted to really bring the piece to live. I purchase some 8 in blue LED light switches from a auto parts store. The package comes with a battery and switch for trying the product in the store. I replaced the switch with a toggle switch from a old microscope(I'm a science and math teacher). From there I drilled a hole into the globe and carefully place the LED strips into the globe. I hid the wire and switch behind the back on the "D". The Discover Logo now glows with a simple switch to turn it on and off.
Cuts some felt fabric to cover the cords in the bottom of the globe using hot glue.
Glue the D and Globe together with some plumbers glue.
Step 7: Final Product
Here is a nice large decorative piece for the office.
