My version of the Dragon Radar, from the Dragon Ball franchise. Based on http://dragonball.wikia.com/wiki/Dragon_Radar
The print is split into multiple parts - the main body will need to be printed twice (front and back), and the grid lines are optional, only print that portion if you're going with translucent filament or plan on making a mold and casting the front lens.
If you want to go with the traditional look from the manga and anime, the front dome can also be used for the back - I just thought it looked a bit plain, so my rear plate adds some details that seemed fitting.
At 100% size, the radar is about 3.75" across. Depending on the artwork, that may be spot on, or may feel small. A 120% size is about 4.5", and may feel better.
