Folgertech i3 2020 Print Cooling Nozzle

thingiverse

This is a mount designed specifically for a print cooling fan on the Folgertech i3 2020 3D printer. It perfectly accommodates one of the common 12V 50mm radial fans with a 15x20mm outlet and provides an ultra-low restriction duct and print cooling nozzle. Mounting the duct requires only two M3 screws to attach to the pre-drilled holes on the left side of the printer's extruder. The fan is designed to press-fit into the top of the duct, so I have not included any other method for securing the fan to the duct. However, I found that the fit was extremely tight and secure, but you may still need to use glue or another attachment method. Every printer's extruder nozzle will be set at a different height based on the mounting of the M6 Teflon tube and nozzle. So, make sure to confirm that the print cooling nozzle is mounted at an appropriate height before printing, and adjust it if necessary using washers or by adjusting the nozzle height. The OpenSCAD file is included for anyone who wants to make adjustments, although you'll need a very recent version of the software to display the elbow joints correctly. The mounting bracket height is easily adjustable through a variable in the code. Unfortunately, Thingiverse's Customizer isn't using a recent enough version of OpenSCAD to work correctly. To-Do: Reprint in higher quality settings and upload better photos. Cura's draft mode can be a bit rough around the edges.
