trigorilla cooling duct

thingiverse

This part attaches a blower fan (similar to this one: https://www.amazon.com/gp/product/B071WMHNG5/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1) to a 2020 extrusion, such as the one used on the Anycubic Kossel printers. The duct distributes air to cool stepper drivers while leaving space for SPI wiring on TMC2130s. When paired with my Kossel Pi Mount (available here: https://www.thingiverse.com/thing:2917902), it also helps cool the Raspberry Pi. This is a friction fit part, and the tab fits snugly into the aluminum frame. The part comes up against the bottom of the heated build plate. It should work as long as you use a material that can withstand heat (I used PETG, but ABS or HTPLA could also be suitable) and the insulation on the bottom of the plate remains intact. UPDATE: A V2 is now available, and I'd appreciate your feedback on which one works better for you.
