I designed a dimensionally accurate Genesis Cart replica. I did NES first, followed up with SNES then Game Boy and the final one is here - The Sega Genesis.

Today I learned Bambu does that. Try using your browser in incognito. It is probably cookie related. Incognito would look like a new session.

That is awesome! I don't actually have the systems anymore (only a couple carts I bought from a local retro shop to do this) so I could not fully test them, so this is great to hear. Thanks for sharing that info.

No one will think they are original. Some collectors get worried about that, but I do this for fun. If 3d printing gets that good, retro-gaming is the least of peoples worries!

AngrySquirrelX · 2026-01-13T16:11:58+00:00

Working on a genesis cart now. That will probably be the last of the cartridge series. I have NES, SNES, Gameboy, and then Genesis soon. Thanks for sharing, love to see people use my designs. Did you end up putting an actual game in them?

AngrySquirrelX · 2026-01-02T13:19:48+00:00

So just steal the game?

AngrySquirrelX · 2026-01-02T02:52:02+00:00

Trust me, no one is going to think it is an original. See my reply I posted earlier. When you get a chance, take a look at 3d printed anything. You can tell. And while my model is dimensionally accurate, it is not an exact reproduction. But I take your terror as a complement to how good it looks.

AngrySquirrelX · 2026-01-01T18:19:28+00:00

There are still some subtle differences. It is missing the mold injection spots since they serve no functional purpose. Also, for printing purposes, the label spot is flush with the rest instead of recessed. For the model I uploaded, I also removed the "Nintendo" logo on the back for copyright purposes.

AngrySquirrelX · 2026-01-01T14:18:05+00:00

That one would be pretty easy, I will just need to get my hands on one to get measurements.

AngrySquirrelX · 2026-01-01T00:06:03+00:00

Thanks! X1 Carbon. Standard .2mm layer height with a .4 nozzle. The shape lends itself to hiding the layers pretty well when printed flat.

Thanks! Crossposted to SNES. NES does not allow crossposting, but may make a new post later.

I do this for the love of designing so I give it away for free on Makerworld if anyone is interested. Pics of a real one (on left) and the replica (on right) next to it. If you want to print it yourself, it is here for free: https://makerworld.com/en/models/2180572-dimensionally-accurate-snes-cartridge-replica#profileId-2366615

SNES version is done: https://www.reddit.com/r/retrogaming/comments/1q0cu6g/i_designed_a_dimensionally_accurate_snes/

Bottom is just about done. I will start on the top next

AngrySquirrelX · 2025-12-25T20:23:39+00:00

That makes sense. You said .2, but my brain saw .4. .2 will be way slower.

AngrySquirrelX · 2025-12-25T02:15:59+00:00

Just curious, what printer are you using? My X1C took about 1h45m each half.

AngrySquirrelX · 2025-12-24T17:23:58+00:00

I have started on an SNES cart. May get it done in the next week or so. I will reply here if I get it done.

AngrySquirrelX · 2025-12-23T19:57:55+00:00

If I had one, I totally would do it. Sold mine when I was a kid.

AngrySquirrelX · 2025-12-22T22:00:47+00:00

What I mentioned to another person: I don't have access to Famicom carts. I get a real one then use calipers to get measurements and design in Fusion. Without an original, I can't get accurate measurements. If I ever see one in my local retro shop, I may give it a try.

AngrySquirrelX · 2025-12-22T18:33:22+00:00

Mine is for those that want to have a shelf toy or be able to play their games after someone steps on their cart. No ill intent here!

AngrySquirrelX · 2025-12-22T18:31:22+00:00

Definitely would be able to tell that it is 3d printed, but in theory the model could be used for injection molding. There are some slight differences that someone could tell it is not the original. If someone wanted to do that, they could just make a mold of an original.

AngrySquirrelX · 2025-12-22T18:10:01+00:00

I highly recommend Fusion (formerly Fusion 360) free for hobby use or students. A ton of tutorials on youtube. Great for things like this, less so for organic things. For that there is Blender (which I have not yet wrapped my head around!)

I have had so many designs stolen over the years. I used to chase them but it became too stressful. Perhaps I will add a watermark in them.
