Prusa INDX 8-Tool Conversion Kit for CORE One/+

Maximum capacity. Up to 8 independent toolheads on one CORE One+. The INDX 8-Tool Conversion Kit is the full-fat version of Prusa's next-gen passive toolchanger — for makers, prototypers and small-batch shops who want every material option ready to go without ever stopping a print.

Looking for the smaller kit? See the INDX 4-Tool Kit (expandable to 8 later).

Why INDX?

• ~12-second true toolchange — no wipe towers, no purge blocks.
• Only ~13 mg of waste per swap — up to 5× less than the most efficient existing systems.
• Induction-heated nozzles for rapid temperature cycling.
• Passive toolheads — no electronics on individual tools, simpler & more reliable.
• LoadCell auto-calibration — ~15 seconds per toolhead.
• Closed-chamber compatible with automatic ventilation.
• Open filament system — works with any 1.75 mm filament up to 300 °C, no proprietary RFID required.

4-Tool vs 8-Tool

The 4-Tool Kit ships with the same Smart Head and a mounting plate that can later be expanded to 8 tools — a great way to start. The 8-Tool Kit gives you the full set day one: 8 tools, 8 spoolholders, every position populated.
