trigorilla cooling duct

This part mounts a blower fan (like this: https://www.amazon.com/gp/product/B071WMHNG5/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1) to a 2020 extrusion like that used on the anycubic kossel printers. The duct splits the air to cool the stepper drivers while leaving room for the SPI wiring on the TMC2130s. If you use it with my kossel pi mount (here: https://www.thingiverse.com/thing:2917902) it will also help cool the raspberry pi.

This is a friction fit part. The tab will snugly fit into the aluminum frame. This comes right up against the bottom of the heated build plate. It should be fine as long as you use a material that can resist heat (I used PETG, but ABS or HTPLA should work fine) and the insulation on the bottom of the plate is intact.

UPDATE: There's now a V2 I have uploaded. Let me know which works better for you.
