Part cooler Geeetech A10 (fan duct for 50mm fan)

thingiverse

This is a huge improvement over the original Geeetech A10 part cooler. I optimized the airflow to maximize the cooling effect. This fan duct leads the air exactly to where you need it without generating turbulences. I tried most of the available part cooling designs on thingiverse but unfortunately, not a single one of them did improve prints for me. So I had to draw my own one. After some iterations I ended up with this design. My extrudr PLA filament tended to warp and curl on overhanging edges with the original part cooler, which led to a very rough bow of the benchy boat and lifted edges on prints that caused problems. Using this design, I am now able to print 100mm bridges without support at 210°C and PERFECT benchy boats. The holes for the 50mm fan are designed in a way that you can just screw in regular M4x20 screws without nuts. The fan duct fits exactly where the original 4015 fan was mounted and is easily screwed in using the four original M2 screws.
