From PlayStation to Reality: How to 3D Print the Metal Gear Solid Codec

With Metal Gear Solid Delta just released, now's the perfect time to commence operations on your very own Codec.

Aside from quotes and impressions in the All3DP office, the recently released MGS3 remake Metal Gear Solid Delta has given us the perfect excuse to check out some creative projects that revolve aound Kojima’s classic.

Gifted creator and YouTuber 3DSage put out the cream of the crop earlier this year on how to build your own MGS communication staple — the Codec.

Designed entirely from zero, 3DSage initially spent days 3D modeling his own compact, infiltration-friendly design before 3D printing the case on a Bambu Lab P1S.

From there, some extra work was required to sneak the 1.8-inch LCD display into the case and an MPU-6050 accelerometer was installed for detecting motion changes.

A cheap walkie talkie was sourced to fulfill the communication aspect, but the microphone was upgraded for enhanced quality. After some intense testing and refinements involving a breadboard and optimized custom circuitboard CNCing, the unit only lacked power, and that’s where a 9 V rechargeable battery with USB-C capability came in.

The project was of course far more complex than we’ve made it out to be here, and includes a jammer, level maps, authentic Codec graphics, and more. So, if you really want to go ahead with the mission, we recommend grabbing yourself a Caloriemate and sitting down to watch the boss himself take you through the joy of this project in his YouTube video. He’s pretty good…
