Here's how I did mine, but you can decorate however you wish.

Getting an injection-moulded look from a 3D print is a labour of love.

With the electronics removed, I applied a base coat of filler spray primer. I wet-sanded the primer with 400-grit sandpaper, and repeated until the surface felt smooth.

I wanted a vibrant, 90s-retro aesthetic, so I chose a bold gradient with highlights:

1. Vallejo Fluorescent Magenta
2. Vallejo Light Yellow
3. Vallejo Light Orange
4. Vallejo Cold White
5. Vallejo Royal Blue

I used an airbrush to create a smooth transition between the orange, magenta, and blue.

I then went in with a small paintbrush to add the yellow details and white stars. I also cleaned up some areas where my masking didn't hold up.

Pro tip: If you're painting a yellow logo like me, paint it white first and then layer the yellow on top.

I also added some charms: My friend got me this charm specifically for the Tamagotchi for my birthday!

Once it was all dry I sprayed it with some enamel clear coat.
