Original E3D heatsink for 3mm filament for the v6 hotend. This parts dissipates the heat quickly, so filament doesn't melt too early.
The 1.75mm Universal v6 Heatsink has been designed to utilize our unique embedded bowden couplings which makes the bowden so compact that we merged bowden and direct into the same product. The product is significantly less bulky than its v5 predecessor.
This product is for direct drive. For a bowden version check this version instead.
