Blower adapter for modified Rapman extruder carriage

thingiverse

Liked chylld's ducted extruder carriage a lot, but decided I wanted to experiment with more airflow. One Sunon blower (PMB1297PYB1-AY.(2).GN though others may fit) and some measuring and there's this. Instructions Sliced with KISSlicer; others may work but no guarantees. Supports in the duct are a bit of a bear to remove, so be a bit careful. Wider end goes into the blower with the motor towards the curved cutout, the other end goes into the portion of chylld's extruder carriage where the PC card blower was intended to go. Tight fit on both sides, may need a bit of sanding; I used epoxy to attach it to the carriage top. Intent is to approximately have the fan's CG towards the centerline of the extruder carriage, with the inlet facing away from the extruder; I'll post pictures of it installed once the epoxy sets.
