About this model

As the name says, this is a printable jacket to convert v6 type hotends to water cooled. It seals to the aluminium heatsink with two O rings so the position of the outlet water pipes can be adjusted (this also helps with dismantling). The printed material of the jacket hides behind the last cooling fin of the heatsink to protect it from the heat block and is water cooled (more insulation between the heat block may be needed). The principal is that if it can keep the filament down its centre cool enough to print then it can keep its self cool enough to survive. The intended use is for enclosed extruders that have a high internal ambient temperature or use high temperature filaments. If you have a 50 degree ambient inside your enclosure then you have to use 50 degree air to cool your heatsin…
