Nintendo 3DS and DS Lite Slim Travel Case

Boost MeIf you're a huge Nintendo nerd like me, consider boosting! I'd love to be able to keep making cool cases and accessories for my favorite consoles :)

Check out my 3DS & DS Game Cartridge Case (18 Games) that is compatible with the cartridge carriers! Do you have too many DS games? then this is perfect! Holding up to 18 games (9 carriers), it makes it so much easier to swap what games you're carrying in a hurry! As well as being a compact way to store your favorite games!

 

Check out my other DS cases:

• new 3DS XL/3DS XL/DSi XL
• new 2DS XL
• 3DS & DS Game Cartridge Case (18 Games)
• OG 3DS and DS Lite
• DSi

This is my take on a travel case for the Nintendo 3DS and the Nintendo DS Lite. This case will safely conceal your 3DS or DS Lite, as well as 6 additional games (7 including the one in the system), or any other accessories that might fit in the accessory slot. I was able to fit either a usb charging cable or two GBA games for the DS Lite. 

 

The dimensions are 192.52mm x 114.96mm x 34.95mm tall.

 

I printed this in Bambu PETG HF for strength. I would also consider using PLA Tough+ as well but have yet to try it!

 

I highly recommend printing all three Cartridge Carriers and using them even if storing less than 6 games since they are only held in place by the lid. If only one or two are used, they will move around a lot more and the games may fall out.

 

I designed the case with the use of 3mm adhesive padded foam which can be found on amazon here.

 

To assemble, you will need six (6) M3x35mm socket head machine screws (I used these from Amazon, which have a head with a 5.4mm diameter and 3mm depth). The screw head clearance is a 6mm diameter.

 

For the foam, you can cut any sizes you'd like for each of the panels, but I will list what I used:

• The bottom of the base and lid each use a 125mm x 70mm piece of foam
• The back side of the base I used 15mm x 15mm pieces on each column as seen in the picture below
• For the sides of the base, I used 65mm x 15mm pieces of foam
• For the front of the base, I used 35mm x 15mm pieces of foam

I've also added plates for lids with the Nintendo 3DS and Nintendo DS Lite logos for anyone storing a specific console!

 

Post your results in the comments with some games and consoles to show off! I'd love to see them!

 

ADDITIONAL NOTES

 

There will be a slight bit of wiggle in the x and y directions for the 3DS, which will not harm the console in any way due to the thick padding. This is to make the clearance also compatible for a DS Lite. 

 

I've also included an additional TPU seal that you can print and superglue into the case, but I will post the results when i print this for myself. Personally, I don't think it is 100% necessary on this model, but included it in case anyone would like to have a slight added layer of sealing/protection to their console.

 

Edit 6.17.2026

I've added a new model/profile while I figure out how I want to store games in the new A1 compatible case! I will upload model photos  when I can but it should print no issue, it has the same internal dimensions as the full-size case. I wil add A1 mini compatible cases for the other DS consoles soon. In the meantime, A1 mini users can also print the 3DS & DS Game Cartridge Case to store games! Enjoy!
