Kossel Mini (K800) J-head retainer and fan duct

thingiverse

Printers require a customized approach with the printed J-head retainer. The Aluminium U-shaped retainer has to be replaced using this specialized component. This particular retaining structure effectively supports two separate cooling systems within it: one designed to cool down the throat pipe and another that handles thermal regulation of actual 3D-printed objects themselves. Users employing the Kossel 800 printer model should check on positioning details as well as adjust duct heights before opting for this change if not using the mentioned specific design. It's also important to update your current fan arrangement because an upgraded duct version, enhanced by a broader intake and thereby reduced turbulence through smart geometry optimization, can significantly reduce unpleasant back-flow effects due to better circulation principles employed within such innovative designs.
