Roll Dispenser for Diaper Bin Refills

A 3D-printable bearing-supported roll dispenser that makes diaper/poop bin refills faster, smoother, and easier.

Instead of struggling with loose rolls, the plastic bag sheet roll is suspended in the air and mounted on bearings. This allows it to rotate freely, so you can effortlessly pull and wind the bag sheet onto your cartridge refill.

✅ Key Benefits:

• Effortless refills → bearings allow smooth, low-friction rotation.
• Hands-free stability → roll stays supported in the air, no slipping or collapsing.
• Reusable & eco-friendly → compatible with long rolls of plastic sheet.
• Compact & printable → easy to print and assemble at home.
• Multi-purpose → works for diaper bins, trash bags, or any continuous roll.

⚙️ How it Works:

1. Place the long roll of plastic sheet on the dispenser.
2. Bearings allow the roll to spin smoothly.
3. Pull the “infinite bag” and wind it onto your refill cartridge (or any core).
4. Insert the cartridge into your diaper/poop bin — done!

🧩 Optional Integration:
This dispenser is part of a larger modular rack system (not included here), so you can combine it with other storage/utility modules if you want to expand later.  https://makerworld.com/en/models/767030-network-rack-modular-rack-system-for-homelab

🎯 Great for:

• Parents tired of tricky diaper bin refills
• Households managing trash bag rolls or storage rolls
• Makers who want a simple, reusable roll dispenser
• Budget friendly parents
