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.
Design Variants Included
The download includes four visual variants, all sharing identical geometry and compatibility:
Circular frame + DIN-style numerals

All variants are designed to look technical, calm, and OEM-like, inspired by classic industrial design principles.
