Bambulab artillery cardboard spool ring v3

Cardboard Spool Adapter Ring for AMS

This adapter ring is designed to improve the usability of cardboard filament spools in AMS (Automatic Material System) units.

Many cardboard spools do not rotate smoothly in AMS systems, which can cause friction, feeding issues, or inconsistent filament movement. This ring solves that problem by being mounted on both sides of the cardboard spool, creating a smooth, rigid rolling surface.

Once installed, the cardboard spool behaves much more like a plastic spool and rotates evenly and reliably inside the AMS.

Features

• Designed specifically for cardboard filament spools

• Improves smooth rotation inside AMS

• Reduces friction and feeding problems

• Easy to install – simply attach one ring to each side of the spool

• Lightweight but rigid design
