High velocity is a must with this setup - narrow exhaust yields higher air velocities. Wide area options are also available. A crucial warning: using this duct limits Y axis movement by approximately 25-30 millimeters. To avoid crashing your machine, use extreme caution! Instructions for Safe Use: The manufacturer does not assume liability in case of mishaps due to misuse of the product. It has come to notice that a minor flaw exists with the STL file. Despite this limitation, it printed perfectly using standard parameters.
