Block V3 and Matchless nozzles

Block V3 and Matchless nozzles for Ultimaker 2

New Block V3 and Matchless nozzles

The Block V3 has 11 significant improvements over the Olsson block - mostly related to heat transfer. The Matchless nozzles have 4 significant improvements and the Matchless Race nozzles have a 5th improvement - mostly related to getting that heat from the block to melting the filament. These heat transfer improvements are significant and allow you to print cooler and/or faster. Matchless nozzles are compatible with Olsson block and older nozzles are compatible with Block V3 but without the extra benefit of faster heat transfer. The Race nozzles are a big improvement even with the "old" Olsson block. More details here.
