Laser-Cut Case

There's a cool resource called MakerCase that allows you to enter dimension for a laser-cut box and it'll give you laser-cuttable files in the dimension you want. Choose flat, finger or t-slot corners.  

In LightBurn I added a few elements:

1. I made a hole in the back panel the same size as my smallest star (1.5 in diameter). This allows me to push the project back out of the box if needed, and also gives the illusion of infinite depth, since I can see all the way through the illusion and out the back.
2. I made a USB port hole in the side panel that will fit my USB-c cable
3. I made a rectangular groove in the top panel to accommodate the width of the NeoPixel strip, so the box will fit snugly around the piece.

3D Printed Box

Another option is to 3d print a case for this project. I used Tinkercad to design and print a pretty color-shifting box using fancy filament. Here's my finished design, including a lid with a window for the front of the box.

Tinkercad is a drag-and-drop 3d modeling program that's free to use and fairly easy to learn. There are ready-made shapes like boxes and cylinders that you can "squish" together and combine in all sorts of creative ways to end up with the shape you want. The tools are pretty basic, but a lot of fun and surprisingly powerful for making 3d models.
