This model is intended for use in cooling the controller of the Solidoodle 2 printer.
One 60mm x 13mm fan, one 3/4" PVC elbow and 4" of 3/4" PVC pipe are required.
This design uses the mount for the filament spool holder on the back of the Solidoodle. Cut 3/4" PVC pipe into 1" and 3" lengths. Insert the pipe sections into the elbow. Push the printed part onto the end of the 3" section. Insert the assembled part into the spool holder such that the printed part is over the controller board. Insert fan into part.
The part may take a little finishing with a deburring tool in order to fit onto the pipe.
