About this 3D model

This is the 6th iteration of my cooling tray, it uses four 30mm fans and its designed for the J-head Mk5B hot end. It has 4 air jets to cool your print evenly and 2 jets to cool the upper peek part of the J-head hot end. It was designed to cool your print and hotend upper part and avoid cooling your table or the melting zone on the hotend.
