The Raise3D upgraded external spool system has a number of advantages over the internal mounted spools.

1. Easy access to the spools without opening the machine.
2. Prints have less chance of layer shifting as the filament is fed directly from above and is, therefore, not pulling from the side.
3. Use any size spool and not be limited to just the Raise3D filaments.
4. Store more than just two spools on the upgrade for rapid filament changing.
5. Comes pre-drilled to allow you the freedom to attach a webcam of your choice to the external system for monitoring long prints
