This Version is similar to available solutions on other platforms but much more stable and stronger (white part at the picture).
Original fans have been used ! Just demount the old housing and mount the new one with the existing fans and get better print quality !
I have printed this in Polymaker PolyMax PLA with standard settings and 100% infill and supports just from the platform.
(by the way... I have decided to print these parts in white instead of back as it improves the visibility of the printed parts during printing!)
