CORE One Indexed Spool Holders (1–8)

CORE One Indexed Spool Holders (1–8)

These indexed spool holders are a functional and visual upgrade for the Prusa CORE One, designed to bring clear filament indexing to multi-spool setups – especially with future INDX Upgrade in mind.

The design is based on the original Prusa CORE One+ Upgrade spool holder, keeping the original geometry, mounting points, and usability fully intact while adding a subtle, OEM-style indexing system.

Each spool holder features a centered index number (1–8), aligned with the original plus-mark position.

The result is a clean, readable identifier that integrates naturally into the machine, without visual clutter or functional compromise.

This model is CORE One INDX-ready, making it ideal for users who want to prepare their setup for organized multi-material workflows from day one.
