Cardboard Spool Protector Ring (200mm)
The Problem: Cardboard Spool Dust Many manufacturers (like ERYONE) are switching to eco-friendly cardboard spools. While good for the environment, they can be a headache for 3D printing enthusiasts. Inside a filament dryer, especially on rotating rollers, the cardboard edge starts to fray and crumble.
Why it matters: Cardboard dust gets everywhere: inside the dryer mechanism and onto the filament itself. Eventually, this dust is pulled into the feed path and extruder, causing clogs.
The Solution I designed this protective ring to cover the rim of standard 200mm cardboard spools.
Perfect Fit: Designed specifically for spools with a 200mm diameter.
Secure Lock: The model features special protrusions (tabs) that fit into the holes on the side of the spool, preventing the ring from slipping or spinning independently.
Smooth Rotation: Makes the spool spin as smoothly as a plastic one and keeps your dryer clean.
Print Instructions
Material: PETG is highly recommended. It is heat-resistant enough to withstand dryer temperatures without deforming (unlike PLA).
Supports: No supports required.
