The Block v3 brings numerous enhancements over the Olsson block. With significant improvements in heat transfer, the Matchless and Matchless Race nozzles enable you to print cooler and/or faster. Matchless nozzles are compatible with Olsson block. Older nozzles are forward-compatible with Block V3, although without the extra benefit of faster heat transfer. Even with the "old" Olsson block, you'll see noticeable improvements while using the Race nozzles.

• 0.25mm
• 0.4mm (race)
• 0.6mm (race)
• 0.8mm (race)
• 1.0mm (race)
• 1.5mm (race)
