Stackable Cube Storage Box (3×3")

A clean, modern stackable cube box that snaps into place on top of another — stack them as high as you want. Comes in two versions:

• Open bin — grab-and-go access with side finger cutouts
• Flush version with lid — closes up for a clean, dust-free look

Originally designed to hold NeeDoh cubes, but it's perfect for anything small: fidgets, desk supplies, hardware, screws, batteries, cables, craft supplies, or kids' toys. Mix open and closed cubes in one stack to build your own modular organizer wall.

Features

• Interlocking stacking lip — cubes align and sit securely, no sliding
• Oval side cutouts double as handles and content windows
• Two styles (open + lidded) that stack interchangeably
• Prints super clean — smooth walls, crisp edges, zero post-processing
• No supports needed
• Compact footprint fits shelves, desks, and drawers

Print Info

• Size: 3" × 3" × 3" (~76 mm cube)
• Supports: None
• Material: PETG, PLA, or whatever you have on hand — pictured prints are PETG HF
• Filament: 61g per box | Print time: 3 hr. 30 min. for all pieces on same plate

You could also add one line under Features since PETG is a selling point:

• Tested in PETG HF for extra durability — but prints just as clean in PLA

Print a few, stack them up, and post a photo — I'd love to see your setups and color combos! If you like the design, a like, boost, or follow helps a ton.
