Testing 30 Steam Deck 3D prints in 30 days. Day 22: Portal Companion Cube Storage Box - not a Steam Deck accessory, but a Valve classic.

✅ 5h 14m print time
✅ 177g filament (multi-color)
✅ 10 minute assembly
✅ Snap-fit design (glue optional)
✅ Functional storage

NOT A STEAM DECK ACCESSORY:
This is the Companion Cube from Portal—another Valve game. Every Steam Deck owner needs to have played Portal, and they need their very own Companion Cube.

MULTI-COLOR PRINT:
White base, pink hearts, matte grey accents. Print quality is fantastic. The multi-color hearts are perfect. Super accurate replica—captures the Companion Cube exactly.

ASSEMBLY:
Corners have pegs that fit into holes in top and bottom. Pieces snap together—fits tight without glue.

I super glued the bottom section for stability, kept the lid removable (lift-off). Ten minutes total. Wait for glue to dry before removing lid, or corner pieces might pop off. Easy to clip back on if they do.

STORAGE FUNCTIONALITY:
Replica first, storage second. Threw in a cable, two USB sticks, SD card—still had lots of room left. Very practical capacity.

There are other storage solutions, but none look this cool.

BUILD QUALITY:
Feels sturdy once assembled. Lid is snug. Fit is really well designed—pieces lock together perfectly.

Really well made replica that you can also use as storage.

PORTAL FAN PERSPECTIVE:
I love Portal. Played it when it first came out. Portal fans will absolutely appreciate this. This one's actually going to a Portal fan as a gift after filming.

THE VERDICT:
Worth printing. Highly recommended. Every Steam Deck owner needs their very own Companion Cube.

"This was a triumph. I'm making a note here: Huge success. It's hard to overstate my satisfaction."

Portal fans: Is the Companion Cube coming home with you?

Verdict: Worth Printing ✅
