Using OpenScad to design Adafruit Trellis casing

Hey there! Spent sometime using OpenScad - 3d design tool. All 3d objects designed programmatically. It was a bit of a pain. I'll probably stick with something as Autodesk Fusion 360 in the future.

The advantage of OpenScad is that you can parametarize your 3d model. For example Trellis box has number of buttons parametirized: you can easily change from 4x4 to 8x4 or 8x8 or other... It as well has height, thickness, etc parameterized. It means that adjusting the model size should be quite easy.

You can use OpenScad to export design into STL and 3d print it.

Below is the screen capture from OpenScad for Trellis 3d model. It as well available at github link.

And here is one of the earlier version print out combined with trellis:
