You ever go to the tennis court, and have a hard time telling your balls from somebody else's? Well, here's my stupid project of the day: The tennis ball stencil.
The procedure is:
In the next step, you'll see how I created the 3-d model.
Step 1: Create your 3D model
I used 3/4" wood to create the stencil. Simply make a 3/4" sheet, and scoop sphere out of it. Tennis balls are 6.7cm in diameter. Leave a mm or two of thickness at the bottom so you don't cut through.
Grab the attached inventor file if you don't want to make your own.
I added all design and g-code files to the attached .zip file. Just download and carve :-)
Step 2: Create the G-CodeCreate the g-code from the 3-d model. I divided carving the sphere into a separate step from carving the smiley face. That way I can make a few spherical templates, then carve different patterns.
Step 3: Carve!
I carved the sphere, then the smiley.
Step 4: Cut out the smiley face!
Using the attached smiley.ngc, you can carve the smiley face :-)
Step 5: Paint
Now, it's a simple matter of holding the tenns ball onto the stencil while spray painting :-)
Wash rince repeat!
