Kossel part cooling fan upgrade
Description
__Motivation__ The original Anycubic Kossel parts cooling fan (40 x 10 mm) started to fail and I wanted to upgrade to a higher airflow with a 50 x 15 mm radial fan (brand: MX). At the same time I upgraded to a 24 V PSU, so I wanted to replace the fan anyway. __Design__ The fan originally had a substantial air-gap between the housing and the fan blades. In an attempt to increase efficiency, I designed the intake duct so that air can smoothly enter the fan while reducing the air-gap. I designed the mount to be glued into the fan housing and using the M2 x 5 screws to mount to the effector. __Print settings__ - Mount: in Cura, use vase mode/ spiral outer contour while printing 20 bottom layers at a layer height of 0.1 mm. This will create a solid base with a thin-walled smooth duct. - Intake duct: rotate so that the flat side is on the bottom. Single wall thickness, 10% infill, support 'touching build-plate'. Use six bottom layers and a layer thickness of 0.1 mm. __Assembly__ - Fit the intake duct first without glue, make sure the fan is free to rotate (it is a tight fit!) before permanently glueing it with CA glue. - Open up the fan mount on the top side (see the fourth picture). - Next mount the fan mount to the effector. - Dry-fit the fan on the fan mount, mark the position. Next remove the fan mount from the effector. Lay it flat on the back side together with the fan and permanently glue it together. - Solder the power wires. __Happy printing!__
