Summary

Approximation of a Sonic & Knuckles Sega Genesis cartridge.

The sides of a real Sonic & Knuckles cap splays slightly outward which this design doesn't try to mimic. That makes snapping into place a little difficult but not impossible. Some other aspects of the real cartridge were omitted such as screw holes and labeling on the back.

Fusion 360 file is provided.

Post-Printing

If the cap doesn't close all the way, some sanding may be needed on the back of the top part of the base piece - if the plastic sags too much while printing, that will get in the way.
