Oreo Cookie Container – Magnetic Lid

 Oreo Cookie Container – Magnetic Lid

A 3D-printed Oreo Cookie you can actually fill.

Overview

The Oreo Cookie Container turns the classic ice cream sandwich cookie into a functional 3D-printed container. Standing 75 mm tall and 150 mm wide, it’s sized perfectly for candies, coins, earbuds, or any little secrets worth hiding in plain sight.

Every fluted ridge, super thick cream layer, and magnetic snap was modeled by hand—no AI assistance—to capture the familiar cookie feel while adding maker-grade precision. Two internal alignment pegs lock the cookie half and the “cream” middle into perfect position, so everything lines up as neatly as a factory stack.

Inside, four 6 × 3 mm neodymium magnets in both halves hold the lid firmly yet release with that smooth slide-off motion shared across the Oreo cookie. It opens like breaking apart a cookie—only cleaner.

Magnetic Lid System

Four 6 × 3 mm neodymium magnets align precisely to hold the lid tight—strong enough to feel secure, yet effortless to open with a simple slide-off motion. For correct polarity every time, use the Magnet Presser with Stand when installing your magnets.

🧩 Why Magnets Instead of Threads

• Smooth Access: no twisting, lifting, or sliding.
• Durability: magnets never strip or seize.
• Cleaner look: preserves the plate-stack silhouette.
• Fast Printing: no need for threaded tolerances or supports.
• Tactile Satisfaction: every open and close gives that solid “click.”

📦 Bill of Materials

• 8× round magnets – 6 mm diameter x 3 mm thick
  • 4 magnets for the lid
  • 4 magnets for the box body
• A drop of CA (super glue) for securing magnets (optional but recommended).

Tip: Mark one face of all magnets with a marker before installation so you keep polarity consistent.

🔧 Assembly Instructions

Tools Needed

• A small amount of CA gel adhesive
• Magnet Presser with Stand (recommended for perfect polarity and depth alignment)
• Optional: Lightweight Hammer

1️⃣ Insert alignment pegs

1. Slide both printed pegs into their slots between the base and the cream layer, and secure the base and cream layer together with gel CA glue.

2️⃣ Install Magnets in the Container

1. Place the first magnet into the Red Magnet Presser.
2. Apply a tiny drop of gel CA into the magnet location of the container. Use the Magnet Presser to press the magnet gently into its pocket.
   • The presser ensures even pressure and prevents chipping or tilting.
   • A small hobby hammer may be needed to press in place.
   • Ensure the magnet is level with the surface or very slightly below.  Note: if the magnet is raised above the surface, a gap will form between the lid and the container. 
   • Repeat for the remaining three recesses using the Red Magnet Presser.

3️⃣ Align and Install Magnets in the Lid

1. Repeat Step 1 for the lid using the Blue Magnet Presser, ensuring the magnet poles face each other and the lid “clicks” shut cleanly every time.

4️⃣ Cure and Test Fit

• Allow adhesive to cure fully (usually 10–15 min).
• Once cured, test-fit the lid. It should align magnetically and slide open with a smooth pull.
