Sparkcube radial fan mount

thingiverse

This is a remix of the "Alternate Fan Mount System" found at Thingiverse (http://www.thingiverse.com/thing:1734379). Since I use the original Sparkcube X-carriage, I redesigned the fan mount plate to suit my needs. The height of the plate can be easily adjusted to match the length of your hotend. I am using two 50mm radial fans, also known as blower fans. I have an E3D Lite6 mounted underneath the X-carriage for cooling the hotend. To cool the hotend, I use a 40mm fan, and you can find the fanduct design on Thingiverse. You can use either the original fan duct or one of the attached fan ducts that I have designed to suit my specific needs. The initial fan duct seems too short for my E3D Lite6 hotend, so I created different variants with increased height. The Sparkcube_Radial_Fan_duct_long_wide_23mm is a longer version with an internal tube distance of 23mm, very close to the heater block of my E3D Lite6. The Sparkcube_Radial_Fan_duct_long_wide_30mm is another longer version but with a wider space between the tubes at 30mm. The Sparkcube_Radial_Fan_duct_30mm is a ring cooler with an internal diameter of approximately 30mm, and it fits well around my heater block. The Sparkcube_Radial_Fan_duct_30mm_incr_gap has the same size as the 30mm ring version but with a small gap at the beginning that increases towards the end (see drawings). The Sparkcube_Radial_Fan_duct_40mm is another ring cooler with an internal diameter of approximately 40mm, which fits well around my heater block. The Sparkcube_Radial_Fan_duct_40mm_flat has the same dimensions as the 40mm versions but with a more flat tube design due to my 40mm fan mount colliding with the fan duct. Assembly: First, print the Sparkcube_Radial_Fan_mount file and one of the fan duct files. Unscrew the sparkcube hotend cooler and use its screws to attach the mounting plate to the X-carriage. Attach your blower fans using a hand drill to create holes where needed (note: there are different versions of blower fans available). Attach the fan duct by pressing the blower fan tubes into the fan duct, then secure it with screws or a zip tie. Just drill a hole in the "flag" part of the fan duct to prevent it from falling off during fast moves. UPDATE: On 2016-12-06, I made some improvements to the 40mm fan duct versions, making them stronger and easier to print.
