Anycubic Kossel TriGorilla Stepper Driver Cooling Fan Duct

thingiverse

I'm trying to create a cooling fan duct for x,y, and z stepper drivers on my TriGorilla board in my Anycubic Kossel Linear Plus 3D printer. I've been using a cooling tunnel for my stepper drivers, but they're not cooling down the ones in the back enough. So, I want to design this fan duct to draw cool air from outside of the printer base. I need it to work with a 40x10mm fan and four M3 screws and nuts, as well as four M4x8 screws and t-nuts. Also, I have to move the board a bit to the left side (towards the power supply) for the fan duct to fix and line up correctly. This design is specifically made for my TriGorilla board on my Anycubic Kossel Linear Plus 3D printer. It might not fit or line up for other delta printers. I've made some changes to this design: * On May 12, 2018, I added a new file called fan_duct_1_40x20.stl for a 40x20mm fan. I haven't tested it yet because I don't have a 40x20mm fan. * I've also updated the fan_duct_2_v1.1 design to add fins that direct the air more towards the drivers.
