Recyclet Cardboard Spool / Organizer

This is my idea: Instead of integrating the cardboard spool into a model,

I thought about reusing and reshaping it to give it a new purpose.

Follow this tutorial to successfully create your own organizer.

Step 1: Assemble the Mold
Secure the base of the mold to the container using M4 screws and nuts.

Step 2: Prepare the Cardboard Pulp

• Cut your cardboard into small pieces and place them in a blender (I don’t know the exact chemical composition of the cardboard, so I used an old blender that I no longer use for food preparation. If you’re comfortable using your regular blender, you may do so at your own risk).
• Add a small amount of water and blend until you achieve a uniform pulp.

Step 3: Make Rice Paste (Natural Glue)

• Cook rice until very soft—this will act as a binding agent.
• Add the cooked rice to the blender and mix again until a smooth, watery paste forms.

Step 4: Drain the Pulp

• Squeeze out as much water as possible from the mixture until it reaches a clay-like consistency. You can use a sieve or simply press it by hand.

Step 5: Fill the Mold

• Press the pulp into the mold, layer by layer, compacting it tightly each time. Repeat until the mold is completely filled.
• To reinforce thin sections (like the lid), add extra pulp and press firmly before closing the mold one final time.

Step 6: Dry Under Pressure

• Place a weight (e.g., a brick) on top of the mold and let it dry for 24 hours.

Step 7: Remove and Final Drying

• Carefully unscrew the base and gently remove the under body.
• Let it air-dry in a warm, dry place (sunlight works well). Once firm, carefully demold it.
• For extra durability, allow it to dry for a few more days before use.

Finished!
Congratulations—you now have a unique organizer! If this project was successful (and fun!), let me know in the comments. If there’s enough interest, I can create larger versions or variations of this design.

Feel free to ask questions—I’m happy to help!
